gnutls_pkcs8_info(3) gnutls gnutls_pkcs8_info(3) NAME gnutls_pkcs8_info - API function SYNOPSIS #include <gnutls/x509.h> int gnutls_pkcs8_info(const gnutls_datum_t * data, gnutls_x509_crt_fmt_t format, unsigned int * schema, unsigned int * cipher, void * salt, unsigned int * salt_size, unsigned int * iter_count, char ** oid); ARGUMENTS const gnutls_datum_t * data Holds the PKCS 8 data gnutls_x509_crt_fmt_t format the format of the PKCS 8 data unsigned int * schema indicate the schema as one of gnutls_pkcs_encrypt_flags_t unsigned int * cipher the cipher used as gnutls_cipher_algorithm_t void * salt PBKDF2 salt (if non-NULL then salt_size initially holds its size) unsigned int * salt_size PBKDF2 salt size unsigned int * iter_count PBKDF2 iteration count char ** oid if non-NULL it will contain an allocated null-terminated variable with the OID DESCRIPTION This function will provide information on the algorithms used in a particular PKCS 8 structure. If the structure algorithms are unknown the code GNUTLS_E_UNKNOWN_CIPHER_TYPE will be returned, and only oid , will be set. That is, oid will be set on encrypted PKCS 8 structures whether supported or not. It must be deinitialized using gnutls_free(). The other variables are only set on supported structures. RETURNS GNUTLS_E_INVALID_REQUEST if the provided structure isn't an encrypted key, GNUTLS_E_UNKNOWN_CIPHER_TYPE if the structure's encryption isn't supported, or another negative error code in case of a failure. Zero on success. SINCE 3.4.0 REPORTING BUGS Report bugs to <bugs@gnutls.org>. Home page: https://www.gnutls.org SEE ALSO The full documentation for gnutls is maintained as a Texinfo manual.
