Hi, I have received a part of JAVA code wich I need to convert to Perl.
This is a part of an encryption sequence on a JAVA based system.
iMode = 0;
String key = "1234567890";
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();
There is no issue in the Twofish part.
My issue is the byte arrays that are being called.
I need to rewrite them to perl, but I am stuck at this part:
byte[] bytes = new byte[256];
how do you create a new 256 byte array in perl.
The objective, to decrypt and encrypt data between Java and Perl.
