gsk_factor_public_key

Factorizes an RSA public key into its component values.

Note: This function is deprecated. Use gsk_factor_public_key() instead.

Format

   #include <gskcms.h>

   gsk_status gsk_factor_public_key_rsa (
                                          x509_public_key_info *  public_key,
                                          gsk_uint32 *            modulus_bits,
                                          gsk_buffer *            modulus,
                                          gsk_buffer *            exponent)

Parameters

public_key: Specifies the public key.
modulus_bits: Returns the length of the modulus in bits.
modulus: Returns the modulus (n).
exponent: Returns the public exponent (e).

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_factor_public_key_rsa() function deconstructs the pkcs_public_key_info into its RSA public key components.
