NAME

X509_digest, X509_CRL_digest, X509_pubkey_digest, X509_NAME_digest, X509_REQ_digest, PKCS7_ISSUER_AND_SERIAL_digest - get digest of various objects

SYNOPSIS

 #include <openssl/x509.h>

 int X509_digest(const X509 *data, const EVP_MD *type, unsigned char *md,
                 unsigned int *len);

 int X509_CRL_digest(const X509_CRL *data, const EVP_MD *type, unsigned char *md,
                     unsigned int *len);

 int X509_pubkey_digest(const X509 *data, const EVP_MD *type,
                        unsigned char *md, unsigned int *len);

 int X509_REQ_digest(const X509_REQ *data, const EVP_MD *type,
                     unsigned char *md, unsigned int *len);

 int X509_NAME_digest(const X509_NAME *data, const EVP_MD *type,
                      unsigned char *md, unsigned int *len);

 #include <openssl/pkcs7.h>

 int PKCS7_ISSUER_AND_SERIAL_digest(PKCS7_ISSUER_AND_SERIAL *data,
                                    const EVP_MD *type, unsigned char *md,
                                    unsigned int *len);

DESCRIPTION

X509_pubkey_digest() returns a digest of the DER representation of the public key in the specified X509 data object. All other functions described here return a digest of the DER representation of their entire data objects.

The type parameter specifies the digest to be used, such as EVP_sha1(). The md is a pointer to the buffer where the digest will be copied and is assumed to be large enough; the constant EVP_MAX_MD_SIZE is suggested. The len parameter, if not NULL, points to a place where the digest size will be stored.

RETURN VALUES

All functions described here return 1 for success and 0 for failure.
