KI_DSAPrivateX957BER
258 RSA BSAFE Crypto-C Library Reference Manual
KI_DSAPrivateX957BER
Purpose:
This KI represents the same algorithm type as KI_DSAPrivate except that it uses the
ASN.1 BER format. It allows you to parse and create an ASN.1 key info type encoded
as specified by X9.57. You call
B_SetKeyInfo to initialize a key object from the
encoded key info type that includes the private component, prime, subprime, and
base. You call
B_GetKeyInfo with this KI to create an encoded key info type from a
key object that was created using
KI_DSAPrivate, KI_DSAPrivateBER, or
KI_DSAPrivateX957BER. The OID for DSA keys, excluding the tag and length bytes, in
decimal, is “
42, 134, 72, 206, 56, 4, 1”. Also see KI_DSAPrivate and
KI_DSAPrivateBER.
Type of information this allows you to use:
the encoding of a DSA private key that is encoded as X9.57 PrivateKeyInfo type that
contains an RSA Security Inc. DSAPrivateKey type. Note that this encoding contains
all of the information specified by
KI_DSAPrivate.
Format of info supplied to B_SetKeyInfo:
pointer to an ITEM structure that gives the address and length of the BER encoding.
The encoding is converted to DER before it is copied to the key object.
B_SetKeyInfo
returns
BE_WRONG_KEY_INFO if the PrivateKeyInfo specifies a private key for an
algorithm other than DSA (as defined by X9.57).
Format of info returned by B_GetKeyInfo:
pointer to an ITEM structure that gives the address and length of the DER encoding.
Can get this info type if key object already has:
KI_DSAPrivate, KI_DSAPrivateBER, or KI_DSAPrivateX957BER.
