AI_KeypairTokenGen
94 RSA BSAFE Crypto-C Library Reference Manual
AI_KeypairTokenGen
Purpose:
This AI allows you to generate the token form of a public/private key pair with a
hardware device.
Type of information this allows you to use:
the parameters for generating the token form of a public/private key pair. The BSAFE
Hardware API (BHAPI) supports token forms of RSA strong key pair generation as
defined in PKCS #1 and DSA key pair generation as defined in FIPS PUB 186.
Format of info supplied to B_SetAlgorithmInfo:
pointer to an A_KEYPAIR_SPECIFIER structure:
where
A_KEYPAIR_DEFINER is defined by:
Format of info returned by B_GetAlgorithmInfo:
pointer to an A_KEYPAIR_SPECIFIER structure (see above).
