X509_ALGOR_new() allocates and initializes an empty X509_ALGOR object, representing an ASN.1 AlgorithmIdentifier structure defined in RFC 5280 section 188.8.131.52. Such objects can specify a cryptographic algorithm together with algorithm-specific parameters. They are used by many other objects, for example certificates, certificate revocation lists, and certificate requests.
X509_ALGOR_free() frees alg.
X509_ALGOR_dup() copies alg by calling i2d_X509_ALGOR(3) and d2i_X509_ALGOR(3).
X509_ALGOR_set0() sets the algorithm OID of alg to aobj and the associated parameter type to ptype with value pval. If ptype is
V_ASN1_UNDEFthe parameter is omitted, otherwise ptype and pval have the same meaning as the type and value parameters to ASN1_TYPE_set(3). All the supplied parameters are used internally so must NOT be freed after this call.
X509_ALGOR_get0() is the inverse of
X509_ALGOR_set0(): it returns the algorithm OID in *paobj and the associated parameter in *pptype and *ppval from alg.
X509_ALGOR_set_md() sets alg to appropriate values for the message digest md.
X509_ALGOR_cmp() compares a and b.
X509_ALGOR_dup() return a new X509_ALGOR object or
NULLif an error occurs.
X509_ALGOR_set0() returns 1 for success or 0 for failure.
X509_ALGOR_cmp() returns 0 if a and b have identical encodings or non-zero otherwise. ASN1_TYPE_set(3), d2i_X509_ALGOR(3), EVP_DigestInit(3), X509_get0_signature(3), X509_new(3), X509_PUBKEY_get0_param(3), X509_signature_dump(3)
