D2I_ESS_SIGNING_CERT(3)                     DragonFly Library Functions Manual

NAME

d2i_ESS_SIGNING_CERT, i2d_ESS_SIGNING_CERT, d2i_ESS_CERT_ID, i2d_ESS_CERT_ID, d2i_ESS_ISSUER_SERIAL, i2d_ESS_ISSUER_SERIAL - decode and encode signing certificates for S/MIME

SYNOPSIS

#include <openssl/ts.h> ESS_SIGNING_CERT * d2i_ESS_SIGNING_CERT(ESS_SIGNING_CERT **val_out, const unsigned char **der_in, long length); int i2d_ESS_SIGNING_CERT(const ESS_SIGNING_CERT *val_in, unsigned char **der_out); ESS_CERT_ID * d2i_ESS_CERT_ID(ESS_CERT_ID **val_out, const unsigned char **der_in, long length); int i2d_ESS_CERT_ID(const ESS_CERT_ID *val_in, unsigned char **der_out); ESS_ISSUER_SERIAL * d2i_ESS_ISSUER_SERIAL(ESS_ISSUER_SERIAL **val_out, const unsigned char **der_in, long length); int i2d_ESS_ISSUER_SERIAL(const ESS_ISSUER_SERIAL *val_in, unsigned char **der_out);

DESCRIPTION

These functions decode and encode signing certificate attribute structures. For details about the semantics, examples, caveats, and bugs, see ASN1_item_d2i(3). d2i_ESS_SIGNING_CERT() and i2d_ESS_SIGNING_CERT() decode and encode an ASN.1 SigningCertificate structure defined in RFC 2634 section 5.4. d2i_ESS_CERT_ID() and i2d_ESS_CERT_ID() decode and encode an ASN.1 ESSCertID structure defined in RFC 2634 section 5.4.1. d2i_ESS_ISSUER_SERIAL() and i2d_ESS_ISSUER_SERIAL() decode and encode an ASN.1 IssuerSerial structure defined in RFC 2634 section 5.4.1.

RETURN VALUES

d2i_ESS_SIGNING_CERT(), d2i_ESS_CERT_ID(), and d2i_ESS_ISSUER_SERIAL() return an ESS_SIGNING_CERT, ESS_CERT_ID, or ESS_ISSUER_SERIAL object, respectively, or NULL if an error occurs. i2d_ESS_SIGNING_CERT(), i2d_ESS_CERT_ID(), and i2d_ESS_ISSUER_SERIAL() return the number of bytes successfully encoded or a negative value if an error occurs.
