To clarify a bit more of the situation
The encryption cipher from JAVA is out of my hands and generated by an API
I somehow need to match the same cipher in perl
JAVA CODE to generate the
Cipher
String key = "just a bunch of text";
byte[] bytes = new byte[256];
byte[] kbytes = key.getBytes();
for (int i = 0; i < bytes.length; i++) {
if (i < kbytes.length) {
bytes[i] = kbytes[i];
} else {
bytes[i] = (byte) i;
}
}
byte[] md5digest = md5DigestAsBytes(bytes);
try {
theGeneratedKey = Twofish_Algorithm.makeKey(md5digest);
blockSize = Twofish_Algorithm.blockSize();
catch (java.security.InvalidKeyException ike) {
throw new Exception(Exception.E_SECURITY, "Invalid security key '
+" + new String(md5digest) + "'", ike);
}
the part that i need a bit help with:
String key = "just a bunch of text";
byte[] bytes = new byte[256];
byte[] kbytes = key.getBytes();
for (int i = 0; i < bytes.length; i++) {
if (i < kbytes.length) {
bytes[i] = kbytes[i];
} else {
bytes[i] = (byte) i;
}
}
byte[] md5digest = md5DigestAsBytes(bytes);
The rest is quite obvious
I am lacking the experience with java to replicate the code and test it against a perl version
Question should read:
I need to match the exact same cipher in Perl
to be able to utilize Crypt::Twofish and decrypt the data.
How can I do this in Perl
