Hash & SHA-256

Does java card 2.2.2 support SHA-256 hash algorithm? In thejava card api there is MessageDigest class and ALG_SHA property. Which algorithm does it really represents? SHA-1 or SHA-256?

Hi,
From MessageDigest in JC2.2.2:
public static final byte ALG_SHA_256 = 4;Cheers,

What version of SQL Server support ssl connection with TLS. 1.2 (SHA-256 HASH)

Hi,
I just want to know,
What version of SQL Server support ssl connection with TLS. 1.2 (SHA-256 HASH).
if support already,
how can i setting.
plz. help me!!!

The following blog states that SQL Server "leverages the SChannel layer (the SSL/TLS layer provided
by Windows) for facilitating encryption. Furthermore, SQL Server will completely rely upon SChannel to determine the best encryption cipher suite to use." meaning that the version of SQL Server you are running has no bearing on which
encryption method is used to encrypt connections between SQL Server and clients.
http://blogs.msdn.com/b/sql_protocols/archive/2007/06/30/ssl-cipher-suites-used-with-sql-server.aspx
So the question then becomes which versions of Windows Server support TLS 1.2. The following article indicates that Windows Server 2008 R2 and beyond support TLS 1.2.
http://blogs.msdn.com/b/kaushal/archive/2011/10/02/support-for-ssl-tls-protocols-on-windows.aspx
So if you are running SQL Server on Windows Server 2008 R2 or later you should be able to enable TLS 1.2 and install a TLS 1.2 certificate. By following the instructions in the following article you should then be able to enable TLS 1.2 encryption
for connections between SQL Server and your clients:

I hope that helps.

Do Mountain Lion and Safari 6.2.2 support SHA-256 Hash algorithms in HTTPS security certificates?

I use SalesForce for my client CRM. I've just received a notice informing me that they are upgrading from SHA-1 hash to SHA-256 for increased HTTPS certificate security. Will my current OS X version (Mountain Lion) and Safari version (6.2.2) support this upgrade?

NEVERMIND! SalesForce provided a test page and I was able to determine that both my Mac and Windows environments and browsers support the upgrade.

Adobe reader x, and win7, sha-1 instead of sha-256

Good afternoon,
i have a problem similar to that posted at
http://forums.adobe.com/message/3707345
i try to sign the pdf (enable for signing with adobe livecycle ES, Right Managements)
but it always is signed with hash algorithm SHA-1
The hardware vendor of the smartcard, says that the problem is an adobe problem, because signing the file with its legacy software all works fine, and with its software the digest is SHA-256 (but the produced file is obviously not a signed pdf..)
For italian law the supported digest is SHA-256, and NOT SHA-1
I'm using the latest adobe reader version (10.1) and Win7
P.S.: adobe livecycle, enabling the pdf for signing with livecycle Right Management Service, put a sign with an adobe certificate and returns a pdf ready to be signed, and in this pdf the adobe sign is SHA-1
could be this the problem?
So, before signing the pdf it just contains an adobe SHA-1 sign (coming from livecycle web service)
With regards

Hi GP,
It's the smart card (or more correctly the software on the smart card) that is the bottleneck to getting to SHA-256. Here's what happens:
NOTE: When I say Acrobat I really mean both Acrobat and Reader
•    The user initiates the signing operation
•    Acrobat asks the user to pick a digital ID
•    The user select a digital ID from the drop-down list on the Sign Document dialog and then clicks the Sign button
•    Acrobat needs to write the file to disk for security purposes (another issue) and puts up the Save As dialog
•    The user selects a file name and save location and Acrobat writes the file to disk and it's at this time two things happen:
    o    The signature appearance is created so it can be part of the signed data (what you see in the signature field is not the signature, but rather a pictorial representation of the signature)
    o    A hole is created in the file and filled with zeros as a place holder where the actual signature will be written
•    Acrobat computes the digest over the file, excluding the hole filled with zeros. By default Acrobat is using the SHA-256digest method
•    Acrobat needs to get the digest encrypted (signed) by the private key associated with the signers digital ID
    o    If Acrobat has access to the private key it calls on the RSA library to do the encryption,
    o    If Acrobat doesn't have access to the private key it sends the SHA-256 digest to the software that does have access to the private key... In your case that's the cryptographic software residing on the smart card
•    It's up to the cryptographic software to feed the 32 byte SHA-256 digest into its encryption algorithm and have the private key encrypt the digest
•    The software on the smart card cannot handle a digest as large as 32-bytes, so it returns an error
•    In Acrobat 9.0.0 and earlier once the error message was returned the signing process was aborted and signature did not get created. Starting with version 9.1 if a PKCS#11 (the specification for smart cards) error is returned Acrobat falls back to re-computing the digest using SHA-1 and starts the process again. It's here where the smart card software is getting the 20-byte SHA-1 digest and can get it encrypted using the private key.
•    Once the encrypted SHA-1 digest (this is really the digital signature) is computed the smart card sends it back to Acrobat
•    Acrobat in turn writes the signature into the hole it created in the PDF file, overwriting the zeros with actual hex values.
And that’s how you get a digital signature based on the SHA-1 digest method. If you absolutely need to use SHA-256 your only option is to get a newer smart card that can handle the larger digest.

How can I at-a-glance review a server's SHA-256 fingerprint in Thunderbird?

All my IMAP sessions are created via SSL/TLS tunnels to the respective servers.
Thunderbird dutifully highlights that the connection is encrypted with the small grey padlock icon in the folder pane. This is helpful.
However, I would like to check the SHA-256 finderprint of the server's certificate on a regular basis, at a glance. Is there a way I can easily do this in Thunderbird?

Hi ITBobbyP,
If I understand correctly, you want to load data from multiple sheets in an .xlsx file into a SQL Server table.
If in this scenario, please refer to the following tips:
The Foreach Loop container should be configured as shown below:
Enumerator: Foreach ADO.NET Schema Rowset Enumerator
Connection String: The OLE DB Connection String for the excel file.
Schema: Tables.
In the Variable Mapping, map the variable to Sheet_Name, and change the Index from 0 to 2.
The connection string for Excel Connection Manager is the original one, we needn’t make any change.
Change Table Name or View name to the variable Sheet_Name.
If you want to load data from multiple sheets in multiple .xlsx files into a SQL Server table, please refer to following thread:

SHA-256 with WebLogic Server

We are being forced to migrate our SSL certs from SHA-1 to SHA-256. We will be using Oracle WebLogic Server 10.3.4 for Oracle FMW Portal. Can anyone tell me if WebLogic supports serving SHA-256 certificates? If so, is there any documentation on this?

You can get in touch with Oracle Weblogic Support and give this bud id : bug8422724
WLS 10.3.1 and above support certificates signed by sha256withRSA.

Why in Firefox there are no cipher suits with SHA-256?

I don't see cipher suits with SHA-256 in Firefox ClientHello. Why? They are not supported?

Set Signature Algorithm to SHA-256 in CSR

running 8.4(5) on ASA5550
im trying to renew the certificate for webvpn, however we have a new requirement that the signature Algorithm should be SHA-256 but when i create the new RSA keys and enroll the trust-point to generate the CSR, i cant find where to change the signature Algorithm and it show
"Signature Algorithm: SHA1 with RSA Encryption"
any advice..

You can't change that on the ASA . Check with your CA the one who is signing the request for you .

ADT error : SHA-256 digest algorithm not available

Hello everyone!
I'm trying to do a real test with my Adobe air projet (wich is working fine on ADL), but when i'm trying to compile it with ADT, I get this error, whatever I write..
Exeption in thread "main" java.lang.RuntimeException: SHA-256 digest algorithm not available

How can I fix this bug?
Thanks

Here is the command I am using to creat myself a new certificate :

I get this error even if I only write "adt". It's very strange..
Thanks for your help !

Signature hash algorithm (e.g. SHA-1, SHA-256...) used in Apple Mail ?

Would anybody know what is the signature hash algorithm being used by Apple Mail ?
And can be selected ?
As NIST recommends the use of SHA-2 in 2011.
I have searched quite a while but no information is found in this area.
Thanks your help in advance !

I've had the same problem now for approximately 6 months. Many of the senders in my inbox are wrong. I haven't changed anything other than upgraded to OS 10.7. It only effects some emails and not all. It is a problem when I search as well because the sender details can't be found
Please help!!!
Thanks.

Hash() - SHA-512 clarification

Does anyone know what algorithm is used in the SHA-512 option for the Hash function?
The CF docs state "SHA-512: Generates an 88-character string using the SHA-1 algorithm specified by FIPS-180-2."
http://livedocs.adobe.com/coldfusion/8/htmldocs/functions_h-im_01.html#1105551
I'm assuming this is a typo, since 256, 384, etc. all state that they use the corresponding algorithm... but can anyone say for sure?
Thanks!

It's most definitely a typo because SHA-512 is part of the SHA2 family
of hash functions.

HASH SHA not working or?

I am trying to return a hash conversion of a string with
SHA-1 algorithm. I expect to see 28-character string but I am
getting 40 character string (probably a hexadecimal)
code is very simple:
<cfset x=hash('a','SHA')>
<cfdump var="#x#">
the output is: 86F7E437FAA5A7FCE15D1DDCB9EAEAEA377667B8
What am I doing wrong?
Thanks
Haluk

The documentation seems inaccurate. 40 char string is normal.

Where's the MD5 or SHA-1 or SHA-256 etc. for the beta downloads?????

there are no links to the checksums on the beta downloads page. Loads of advertising though. The difficulty of entering this support information would thwart over 95% of all feedback. This is so obvious but what is also continuously obvious to me is the incompetence of software organizations (commercial or open source). PULL YOUR HEADS OUT. Never make someone search for duplicate bugs on a bug submission page. You people make spyware CHROME look viable!!!
