KI_PKCS_RSAPrivateBER
278 RSA BSAFE Crypto-C Library Reference Manual
KI_PKCS_RSAPrivateBER
Purpose:
This KI is similar to KI_PKCS_RSAPrivate except that it uses the ASN.1 BER format.
This KI allows you to parse and create an ASN.1 key info type that is encoded with
the PKCS #8 standard. You call
B_SetKeyInfo to initialize a key object from the
encoded key info type that includes the modulus, exponents, two primes, and
Chinese Remainder Theorem information. You call
B_GetKeyInfo with this KI to
create an encoded key info type from a key object that was created using
KI_PKCS_RSAPrivate, KI_PKCS_RSAPrivateBER or KI_RSA_CRT. The OID for RSA PKCS
#1 encryption, excluding the tag and length bytes, in decimal, is “
42, 134, 72, 134,
247, 13, 1, 1, 1
”. Also see KI_PKCS_RSAPrivate.
Type of information this allows you to use:
the encoding of an RSA private key that is encoded as a PKCS #8 PrivateKeyInfo type
that contains a PKCS #1 RSAPrivateKey type. Note that this encoding contains all of
the information specified by
KI_PKCS_RSAPrivate.
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 the RSA algorithm.
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_PKCS_RSAPrivate, KI_PKCS_RSAPrivateBER or KI_RSA_CRT.
