Skype password is saved as MD5 hash in Config.xml

github.com/rapid7/metasploit-framework/pull/3473
So if some trojan software can steal your config.xml, it won't take long to get a password.

We’re aware of an industry-wide technique that would require a would-be attacker to already have access to the targeted machine in order to pull passwords – a situation that is not a security boundary, according to the Ten Immutable Laws Of Security: http://technet.microsoft.com/en-us/library/cc722487.aspx.

JPasswordField and MD5 hashes

I have two methods to make an MD5 String from an entered password in a JPasswordField. Which one is better for security? Can anyone recommend any changes?
* Create MD5 of password field
* @param JPasswordField - location of the password
* @return String - an MD5 hash of the field text
private String getMD5(javax.swing.JPasswordField field) {
    java.security.MessageDigest md;
    String passwdString = "";
    char[] passwdChars = field.getPassword();
    int i;
    field.setText("");
    // char[] to string and blank out chars
    for (i = 0; i < passwdChars.length; i++) {
        passwdString += passwdChars;
passwdChars[i] = 0; // blank after for security
try {
md = java.security.MessageDigest.getInstance("MD5");
} catch (java.security.NoSuchAlgorithmException e) {
return null;
byte[] passwdMD5 = md.digest(passwdString.getBytes());
passwdString = "xxxxxxxxxxxxxxxxxxxxxxxxx"; // security
return dumpBytes(passwdMD5);
* Create MD5 of password field
* @param JPasswordField - location of the password
* @return String - an MD5 hash of the field text
private String getMD5a(javax.swing.JPasswordField field) {
java.security.MessageDigest md;
String MD5;
try {
md = java.security.MessageDigest.getInstance("MD5");
} catch (java.security.NoSuchAlgorithmException e) {
return null;
MD5 = dumpBytes(md.digest(new String(field.getPassword()).getBytes()));
field.setText("");
return MD5;
* Byte[] to String conversion
* @param byte[]
* @return String
private static String dumpBytes(byte[] bytes) {
int i;
StringBuffer sb = new StringBuffer();
for (i=0; i<bytes.length; i++) {
if (i%32 == 0 && i!=0) {
sb.append("\n");
String s = Integer.toHexString(bytes[i]);
if (s.length() < 2) {
s = "0"+s;
if (s.length() > 2) {
s = s.substring(s.length()-2);
sb.append(s);
return sb.toString();

Thanks for the replies.
Unfortunately I can't get the charsToBytes function to work. For example, if you run the following code you can see that it doesn't seem to give me the correct md5 (if you to to http://pajhome.org.uk/crypt/md5/ and calculate the MD5 for 'test' you will see that function getMD5a works but not getMD5b):
public class test {
    public static void main(String args[]) {
        new test();
    public test() {
        char[] chars = {'t','e','s','t'};
        System.out.println("Method a: "+getMD5a(chars));
        System.out.println("Method b: "+getMD5b(chars));
    private String getMD5a(char[] passwd) {
        java.security.MessageDigest md;
        String MD5;
        try {
            md = java.security.MessageDigest.getInstance("MD5");
        } catch (java.security.NoSuchAlgorithmException e) {
            return null;
        MD5 = dumpBytes(md.digest(new String(passwd).getBytes()));
        return MD5;
    private String getMD5b(char[] passwd) {
        java.security.MessageDigest md;
        String MD5;
        try {
            md = java.security.MessageDigest.getInstance("MD5");
        } catch (java.security.NoSuchAlgorithmException e) {
            return null;
        MD5 = dumpBytes(md.digest(charsToBytes(passwd)));
        return MD5;
    public static byte[] charsToBytes(char[] chars) {
        byte[] bytes = new byte[chars.length*2];
        int b,c;
        for (b = 0, c = 0; c < chars.length; c++, b+=2) {
            bytes[b] = (byte)((chars[c] >> 8) & 0xFF);
            bytes[b+1] = (byte)(chars[c] & 0xFF);
        return bytes;
    public static String dumpBytes(byte[] bytes) {
        int i;
        StringBuffer sb = new StringBuffer();
        for (i=0; i<bytes.length; i++) {
            if (i%32 == 0 && i!=0) {

Migrate users from qmail to sun messaging (import MD5 hashed passwords)

Hi,
we are planning to migrate about 2000 users from our current mail system (qmail + openldap) to Sun Messaging 6.2.
We have encountered a problem with user password migration. In our current ldap user passwords are MD5 encrypted, but it appears as Directory 5.2 does not support MD5 encryption method.
This is what I have found :
http://docs.sun.com/source/817-7616/config.html#wp26092
The following encryption types are supported by Directory Server:
* SSHA (Salted Secure Hash Algorithm) is the recommended method as it is the most secure.
* SHA (Secure Hash Algorithm). This is the method supported by 4.x Directory Servers.
* CRYPT is the UNIX crypt algorithm. It is provided for compatibility with UNIX passwords.
* If this attribute is set to CLEAR, passwords are not encrypted and appear in plain text.
We want to import MD5 hashed passwords so users can use their old password after we migrate to SUN, but as passwords are updated they will be SSHA hashed.
We only have a problem with importing MD5 hashed passwords in ldap directory.
Current password on openLDAP are created with the following PHP code:
$info["userPassword"]= '{md5}' . base64_encode(pack('H*', md5($passwd)));
I have tried to copy userpassword value from openldap to directory but the directory ignores {md5} and hashed the string again using SSHA.
Example:
cleartextpass: password
md5_base64_hash={MD5}X03MO1qnZdYdgyfeuILPmQ==
after ldap modify userpassword field loks like this:
userpassword:{SSHA}a+dFsejrTGwQAgdU07kkgzWWOC16SiIW2UsPcQ==
What is the correct procedure to import MD5 hashed passwords in Sun Directory?
(NS-MTA-MD5 Password Storage Plug-In is enabled)

Sun Directory 5.2 has a plugin NT-MTA-MD5 which should enable users to authenticate with MD5 hashed passwords.
I have checked in cn=config and NS-MTA-MD5 plugin is enabled.
I have tried with {NS-MTA-MD5} prefix and still directory does not allow users to authenticate.
Example:
cleartextpass: foo
md5_base64_hash={NS-MTA-MD5}rL0Y20zC+Fzt72VPzMSk2A==
after ldap modify userpassword field loks like this( NS-MTA-MD5 is accepted by directory):
userpassword:{NS-MTA-MD5}rL0Y20zC+Fzt72VPzMSk2A==
but
ldap bind fails with "invalid credentials" error
We are using solaris 10 so I tried using the prefix {crypt} and it did not work. You said something about the right config in /etc/security/crypt.conf. Here is the content of my crypt.conf file:
1 crypt_bsdmd5.so.1
2a crypt_bsdbf.so.1
md5 crypt_sunmd5.so.1
This should be the right config "md5 crypt_sunmd5.so.1"
Am I missing something here?
Is there anything else I need to do to enable directory to use MD5 hashed passwords?
Maybe NS-MTA-MD5 plugin is not enough?

Why can't I delete a user name and password from saved passwords in iOS 7?

Why can't I delete a user name and password from saved passwords in iOS 7? I found them and they are not anything that I am familiar with? They are from a t-com.de. I have been to Germany in the last month. Not sure if there is any association. Any thoughts?

You found them ... where? Are they in Safari somewhere?
If so, do Settings > Safari > Clear History and Settings > Safari > Clear Cookies and Data
If that doesn't clear them (and they are from Safari), try Settings > Safari > Advanced > Website Data and clear that area.

My facebook password is saved, but I changed it and the old password automaticly inserts, I need to change it.

I changed my password for facebook. The old password was saved and automatically filled in each time I log into facebook. The old password still fills in and I need to know how to change it to the new one.

Tools -> Options -> Security -> Saved Passwords.
On the list of sites select http://www.facebook.com (you should see your FB user name in the right column). Select "Remove". Login to FB with your new password and click "Remember password" when asked.

Let me reset my ----- SKYPE ---- password

Okay so I don't know what the hell is going on with this messed up useless system you have going on here, but I got locked out of skype for some insane reason since I didn't change my password (hell it stopped on autoload!). And when I go to get my password reset by sending the email to my linked account...
It resets my microsoft password!
Seriously WTF. They use different passwords! Why in the flaming hell would resetting my microsoft password help? If signing in with it that way worked, sure, but that option hasn't worked since it's been installed. Let me reset my damed skype password please for gods sake!

Same problem here.

The selected signed file could not be authenticated. The file might have been tampered with or an error might have occured during download. Please verify the MD5 hash value against the Cisco Systems web site

I am trying to load any 9.0.3 firmware on my UCM 5.0.4.2000-1 server. Every newer firmware I load throws the following error. I have verified the MD5 is correct and also downloaded the file several times with the same result. I can load the same firmware file on another UCM server and it loads fine. Any ideas?
Thanks in advance!

Firmware File: cmterm-7970_7971-sccp.9-0-3.cop.sgn
UCM version: 5.0.4.2000-1

Thanks for your reply. We have a lab environment where I maintain UCM 5.0, 5.1, 6.0, 6.1, 7.0, 7.1 and 8.0 servers each running the latest released firmware for our QA testing team. I have downloaded and installed the latest device packages but find that if I try to install any firmware newer then 8.3.1 on either 5.0.4 or 6.0 i start getting MD5 hash authentication errors. It looks like 9.0.3 firmware should work on UCM 5.0 and 6.0 so I am lost as to why I can't seem to update any firmware for any model phone if it is newer then version 8.3.1 on either 5.0 or 6.0. while 5.1 and 6.1 work without issues. Maybe it is just a bug. I mostly wanted to see if anyone else has experienced this or if it is just me.

MD5 hash code in PLSQL

Hi everyone,
I am building dynamic web pages using Oracle's plsql web
toolkit. I am building a page that will pass information to a
credit card authorizer. I need to create a MD5 hash string to
pass to the credit card company. Is there an Oracle built in
procedure/function/package to generate a MD5 hash string? If
not, can anyone recommend a good reference source for generating
a MD5 hash code in a plsql environment.
Thanks.
Dave W.

This is from the Object API; I think it has the information that explains what's happening (but doesn't resolve your apparent problem)
public int hashCode()
Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable.
The general contract of hashCode is:
Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results.
However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hashtables.
As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)

Keychain: What happened to "passwords not saved"?

I was about to answer this question by directing the user to Keychain Access, where he could find the relevant website and simply delete it.
For as long as I've known, if you tell a website to never save passwords for it, Safari would create a Keychain entry with the website URL along with the note "passwords not saved". From that moment on, Safari would not ask if you'd like to save the password. The Keychain entry was self-explanatory; if you asked Keychain to show the password the field would be blank.
So, I checked my Keychain for the several secure financial websites where I store various amounts of the enormous Galt wealth all over the globe. They're not in Keychain any more - they're gone completely!
I suspect this happened when I updated Safari from 4.0.4 to 4.0.5, since I got the familiar popup "Keychain has been updated" etc.
Something must tell Safari not to ask to store a password for a particular website, and without a Keychain entry, it can't be the Keychain, right? So what is it now? A cookie?

Thanks, BD, this makes sense to me, though I can't seem to find a Login keychain I think I understand what's going on now.
The difficulty seems to be function of how Safari interacts with secure websites, and that's changed with Safari's evolution. At one time Safari would give you the option of saving names and passwords no matter what. They were stored in Safari's Autofill preferences while the actual passwords were stored in the Keychain. Later, it appears that Safari began to honor a secure website's request to not even do that, so I'm never given the choice. Those Keychain entries disappeared.
Firefox behaves differently still. At least one secure website will not allow Safari to autofill, but the same one will autofill with Firefox. It requires a ridiculously secure, non-memorable password, such as U*ng%!+{&.4 - you know, the kind you have to write on a Post-It note stuck to your monitor since it expires every 36 hours. It's a government website and by definition, stupid. For that one I use Firefox.
I would surmise that if the internet standards allow for a choice, Apple is taking the more secure route.
So, some websites, even though their address starts with https:// allow Safari to store names and passwords. I surmise that some do not; for those Safari will not even give you the option. I was looking for those in my Keychain - now they're gone, and I guess that's the way it's going to be!
You deserve a by the way, but I had clicked "Helpful" before I unraveled this mystery. Sorry!

Don't have Skype password, can't login

I'm trying to login to skype, I know my name but don't know the password. I clicked the button to recover the password which reset my Microsoft account password (?) Now I can log into my Microsoft account, but then it asks me for my Skype password to link the accounts which I don't have.
I tried to recover the SKYPE password a second time and it says that I can only do that once every 24 hours.
Help?

Every mail account has a password. So lets start at the beginning.
Have you added your account to Thunderbird?
Do you know the email password issued by your mail provider? If not ask them!

Cisco ISE NTP MD5 hash is 20-Bytes?

When attempting to configure an NTP authentication-key in the Cisco ISE CLI I noticed that it will not accept an md5 hash of 32 characters (16 bytes). Instead it is expecting a 40 character (20 bytes) hash. That is in line with a SHA-1 hash, not an MD5 hash even though there is no SHA-1 keyword, only an MD5 keyword.
What's the deal?
Cisco ISE Version: 1.1.2.145 (Update 3)
ise/user(config)# ntp authentication-key 75 ?
md5 MD5 authentication
ise/user(config)# ntp authentication-key 75 md5 hash ?
<WORD> Hashed key for authentication (Max Size - 40)
ise/user(config)# ntp authentication-key 75 md5 hash 12345678901234567890123456789012
% ERROR: Bad hashed key.
ise/user(config)# ntp authentication-key 75 md5 plain test
ise/user(config)# do show run | i md5
ntp authentication-key 75 md5 hash 97dc37c94236ec1b4c56871c2e482cbd6f56bd33
That's not an MD5 hash as it's 40 characters long (20 bytes).

Hmm, that is an interesting observation. I am guessing that it is a typo and should be "sha-1" because 40 characters is definitely not MD5 :)
I would suggest you open a case with Cisco TAC and report this. If you get a bug ID or a different answer please let us know.
Thank you for rating helpful posts!

DBMS_CRYPTO MD5 hash value does not match 3rd party MD5 free tool

Hello,
I am using Oracle Version: 11.2.4.
I have a problem where the MD5 value from DBMS_CRYPTO does not match the hash value from 3rd party MD5 free tool (MD5 Checksum Calculator 0.0.5.58 or WinMD5Free v1.20) and also the MD5 hash value calculated by an ingestion tool where I am transferring files to. The MD5 hash value that the ingestion tool calculates is the same as the 3rd party MD5 free tools I have. This occurs only on some of the XML files that I generate using XSQL(xmlserialize, xmlagg, xmlelement, etc.) and DBMS_XSLPROCESSOR on a Linux OS. The XML files are transferred from the Unix OS to my Windows 7 OS via filezilla.

And in that thread (Re: MD5 HASH computed from DBMS_CRYPTO does not match .NET MD5 I provided the reason why DBMS_CRYPTO may not match hashes produced by other methodologies.
I have no idea why you copied and posted all of that Java code the other poster and I provided since code has NOTHING to do with the problem you say you are having. Thte other poster's question was how to write Java code that would produce the same result as DBMS_CRYPTO.
You said your problem was understanding why DBMS_CRYPTO 'does not match the hash value from 3rd party MD5 free tool ...'. and I answered that in the other forum.
>
The Crypto package always converts everything to AL32UTF8 before hashing so if the .NET character set is different the hash will likely be different.
See DBMS_CRYPTO in the PL/SQL Packages and Types doc
http://docs.oracle.com/cd/B28359_01/appdev.111/b28419/d_crypto.htm
If you look at the spec header for the DBMS_CRYPTO package it shows this note:
-- Prior to encryption, hashing or keyed hashing, CLOB datatype is
-- converted to AL32UTF8. This allows cryptographic data to be
-- transferred and understood between databases with different
-- character sets, across character set changes and between
-- separate processes (for example, Java programs).
-- If your 3rd party MD5 free tool (MD5 Checksum Calculator 0.0.5.58 or WinMD5Free v1.20) do not use the AL32UTF8 character set then the hashes will likely be different. You can't modify DBMS_CRYPTO so if the hashes need to match you need to use 3rd party tools that either use the correct character set or can be configured to use the correct character set.
The problem in the other thread was how to WRITE Java code that uses the correct character set and I showed that OP how to do that.
So unless you are writing your own Java code all of that code you copied and pasted is useless for your use case.

Quote from the article.
Time Machine in OS X Lion includes a new feature called "local snapshots" that keeps copies of files you create, modify or delete on your internal disk. Local snapshots compliment regular Time Machine backups (that are stored on your external disk or Time Capsule) giving you a "safety net" for times when you might be away from your external backup disk or Time Capsule and accidentally delete a file.
So what makes a notebook any different then a desktop, other then with a desktop you might have your tm backup drive connected all the time.
The object here is to not indiscriminately delete files you need or want to keep. I personally have never deleted a file I wanted to keep.
In essence a backup is for catastrophic failure of your system. So it can be restored once that failure has been fixed. Not because you go in willy nilly and start deleting files.
