Hi,
I am currently working on IcedTea and trying to get the testcase
attached to the bug report [1] working. I need to implement the
PBEWithMD5AndDES algorithm. I am wondering if anyone can point me
in the right direction? I do not have much experience with crypto.
This is not implemented in Classpath either, so it will be worth
implementing.
I'm pretty sure that "PBEwithMD5andDES" in the JDK's parlance refers
to RSA's password-based encryption spec, PKCS #5, version 1.5 [1].
The "MD5" refers to the MD5 MessageDigest, and the "DES" the DES Cipher.
The way to go here is to write a generic PBE implementation, and
subclass it for each hash and cipher combination in Classpath. This
shouldn't be too difficult, since the MessageDigest and Cipher bits
are already implemented.
Classpath implements a later (alas, incompatible) version of this
spec, in gnu.javax.crypto.jce.cipher.PBES2.
