AI_SHA1Random
AI_SHA1Random
Purpose:
This AI allows you to generate a stream of pseudo-random numbers which are guaranteed to have a very high degree of randomness. Random numbers are used in deriving public and private keys, initialization vectors, and so on. This AI uses SHA1 as an underlying hashing function. The details of this algorithm are available from RSA Laboratories' Bulletin #8 or online at http://www.rsasecurity.com/rsalabs/ bulletins/.
Other algorithms that can be used to generate pseudo-random numbers are AI_MD2Random, AI_MD5Random, and
Notes:
In this API, AI_SHA1Random is identical to AI_X962Random_V0 (Section 2.97); however, this identification may change in future versions of Crypto-C. For forward compatibility, we recommend that you do not use the name
applications; use AI_X962Random_V0 instead.
AI_X962Random_V0 provides an implementation of SHA1 Random that is based on the X9.62 standard; this is different from the implementation of SHA1 Random in RSA Security Inc.'s Java cryptographic toolkit, RSA BSAFE Crypto-J . Future versions of Crypto-C may implement AI_SHA1Random in a manner compatible with the implementation provided via the “SHA1Random” value passed to the
class in Crypto-J.
