NAME
X509_signature_dump,
X509_signature_print —
SYNOPSIS
#include <openssl/x509.h>
int
X509_signature_dump(BIO *bio,
const ASN1_STRING *signature, int
indent);
int
X509_signature_print(BIO *bio,
const X509_ALGOR *algorithm, const
ASN1_STRING *signature);
DESCRIPTION
X509_signature_dump() writes the data bytes contained in
the signature to bio in
hexadecimal format with colons between bytes, 18 bytes per output line, each
line indented with indent space characters.
X509_signature_print() writes the name of
the signature algorithm, or, if no name for it is
known, its object identifier (OID) to bio using
i2a_ASN1_OBJECT(3).
After that, if a method object for the algorithm can be retrieved with
EVP_PKEY_asn1_find(3)
and if that object defines a printing method, that printing method is used
to print the signature. Otherwise, unless the
signature is NULL, it is
printed using X509_signature_dump().
RETURN VALUES
These functions return 1 on success or 0 on failure. They fail and return as soon as any write operation fails.SEE ALSO
