Hacker Cracks Secure Hashing Algorithm Using Amazon CloudUsing EC2's cluster GPU power, security researcher spent only $2.10 to decrypt 14 SHA1 passwords in under an hour; other experts aren't concerned.
Fortunately mainframe has no GPU <vbg>
more seriously:
1. Passwords in RACF db are stored using DES, not SHA (actually the
password is the key used to encrypt the userid).
2. It's wide known that SHA1 is not enough strong.
3. The best idea is not to share RACF db with potential hackers. No db
means nothing to crack, doesn't matter neither algorithm, nor CPU power
available for cracking.
