Chapter 2 Algorithm Info Types 51
AI_DSA
Input constraints:
The DSA algorithm requires that the input data (the data to sign) be exactly 20 bytes
long. Normally, this 20-byte input is the result of SHA1 output.
Output considerations:
The
signature
result of B_SignFinal will be 40 bytes long; these bytes appear in the
order (
r
,
s
).
Token-based algorithm methods:
AI_DSA may be used to access the hardware-related algorithm methods
AM_TOKEN_DSA_SIGN and AM_TOKEN_DSA_VERIFY for use with BHAPI.
Token-based key info types:
When used with one of the hardware algorithm methods listed above, AI_DSA should
be used with
KI_Token or KI_KeypairToken.
