Hi Team,
We are from HCL-Cisco team.
Recently we got a request to support the HMAC-SHA2-256 and HMAC-SHA2-512
stronger algorithms.
At present, we are using the “jcraft.jar” of version:0.1.53 and downloaded
the latest “0.1.55” also.
In that jar, particularly – com.jcraft.jsch.JSch.java found the below lines
are commented out,
// The "hmac-sha2-512" will require the key-length 2048 for DH,
// but Sun's JCE has not allowed to use such a long key.
//config.put("hmac-sha2-512", "com.jcraft.jsch.jce.HMACSHA512");
Why this algorithm is not yet supported? But still I am able to see the
file named com.jcraft.jsch.jce.HMACSHA512.
Is this algorithm not fully implemented/handled with Parent
Class“HMAC.java”?
Suggest if any alternate way to support SHA2-512 algorithm ?
And also I would like to know the list of all types of MAC algorithms
support in Java till date.
Thanks in Advance !
Regards,
Mohamed Faleh N
