There were many reasons behind it, but a significant one was that DSA
signing keys and Elgamal encryption keys were not patented. It is
difficult to establish a new protocol if a major chunk of it is
patented. SHA1 was the state of the art hash then, and an obvious
AES256 is not the default cipher. 3DES is.
