Hi All,

In my project SHA encryption is being used for encryption.
I have received a request to migarte this to a 64 bit algo so that it is more secure.

All i wanted to know is , when we write:

MessageDigest digest = MessageDigest.getInstance("SHA");


which version of SHA is called ( SHA-1 or any other )

so that I can trace it and study the encryption scheme used.

Thanks

I'm not sure what you mean by "64-bit algo". SHA-1 (which I assume you're using) creates 160bit digests.

Java also supports "SHA-256", which creates 256bit digests.

(Note that SHA is a hash -or digest-, not a cipher. So any "encryption" it's used for would be one-way.)
