   gsk_status gsk_construct_private_key_rsa (
                                          gsk_buffer *             modulus,
                                          gsk_buffer *             public_exponent,

                                          pkcs_private_key_info *  private_key)

Parameters

modulus: Specifies the modulus (n).
public_exponent: Specifies the public exponent (e).
private_exponent: Specifies the private exponent (d).
prime1: Specifies the 1st prime (p).
prime2: Species the 2nd prime (q).
prime_exponent1: Specifies the private exponent d modulo p-1
prime_exponent2: Specifies the private exponent d modulo q-1.
coefficient: Specifies the CRT coefficient q^-1 mod p.
private_key: Returns the private key

Results

The function return value will be 0 if no error is detected. Otherwise, it will be one of the return codes listed in the gskcms.h include file. These are some possible errors:

[ASN_ELEMENTS_MISSING]: Required data element is missing.

Usage

The gsk_construct_private_key_rsa() function constructs pkcs_private_key_info from its RSA private key components. The pkcs_private_key_info structures x509_algorithm_identifier is set with x509_alg_rsaEncryption, while version specifies 0.
