Table 4-4 Pseudo-Random Number Generation
Algorithm Info Type Description
AI_MD2Random MD2 pseudo-random number generator
AI_MD5Random MD5 pseudo-random number generator
AI_SHA1Random Identical to AI_X962Random_V0. For forward compatibility,
we recommend that you use AI_X962Random_V0.
AI_X931_Random Generates pseudo-random numbers for RSA key generation in
conformance with ANSI X9.31 standard. This AI is intended for
use with AI_RSAStrongKeyGen only.
AI_X962Random_V0 SHA1 pseudo-random number generator based on X9.62
