gnutls_pk_algorithm_t gnutls_openpgp_crt_get_subkey_pk_algorithm(gnutls_openpgp_crt_t key, unsigned int idx, unsigned int * bits);
- gnutls_openpgp_crt_t key
- is an OpenPGP key
- unsigned int idx
- is the subkey index
- unsigned int * bits
- if bits is non null it will hold the size of the parameters' in bits
DESCRIPTIONThis function will return the public key algorithm of a subkey of an OpenPGP certificate.
If bits is non null, it should have enough size to hold the parameters size in bits. For RSA the bits returned is the modulus. For DSA the bits returned are of the public exponent.
RETURNSa member of the gnutls_pk_algorithm_t enumeration on success, or GNUTLS_PK_UNKNOWN on error.
