The predominant form of education system in the U.S. does not reward kids following their natural talents. The reason is that talents are considered "extra-curricular." Strict and rigid curricular legislation is at fault.

I suppose it's easy to implement in COBOL.

3DES is still secure (it has an effective key length of 112 bits, which cannot be brute forced). The problem is it's slow -- much slower than any of the NIST finalists.

you're referring to password hashing, where the security has nothing to do with collision resistance of the hash function. He can do the same thing with SHA512, for example.

Either way, its not secure and hasn't been for a while. There was some news about it recently... some guy was using Amazon EC2, he cracked liked 14 hashes in under an hour.

No they didn't. They found a collision in SHA-0.

In February 2005, a group at Shandong University in China found collisions in the full version of SHA-1.
