Function Documentation

◆ tor_tls_cert_get_key()

crypto_pk_t* tor_tls_cert_get_key ( tor_x509_cert_t *  cert)

Return a newly allocated copy of the public key that a certificate certifies. Watch out! This returns NULL if the cert's key is not RSA.

◆ tor_tls_cert_is_valid()

int tor_tls_cert_is_valid ( int  severity,
const tor_x509_cert_t *  cert,
const tor_x509_cert_t *  signing_cert,
time_t  now,
int  check_rsa_1024 
)

Check whether cert is well-formed, currently live, and correctly signed by the public key in signing_cert. If check_rsa_1024, make sure that it has an RSA key with 1024 bits; otherwise, just check that the key is long enough. Return 1 if the cert is good, and 0 if it's bad or we couldn't check it.

◆ tor_x509_cert_decode()

tor_x509_cert_t* tor_x509_cert_decode ( const uint8_t *  certificate,
size_t  certificate_len 
)

Read a DER-encoded X509 cert, of length exactly certificate_len, from a certificate. Return a newly allocated tor_x509_cert_t on success and NULL on failure.

◆ tor_x509_cert_dup()

tor_x509_cert_t* tor_x509_cert_dup ( const tor_x509_cert_t *  cert)

Return a new copy of cert.

Definition at line 138 of file x509.c.

◆ tor_x509_cert_free_()

void tor_x509_cert_free_ ( tor_x509_cert_t *  cert)

Free all storage held in cert

Definition at line 75 of file x509.c.

References memwipe(), and tor_free.

◆ tor_x509_cert_get_cert_digests()

const common_digests_t* tor_x509_cert_get_cert_digests ( const tor_x509_cert_t *  cert)

Return a set of digests for the public key in cert.

Definition at line 68 of file x509.c.

◆ tor_x509_cert_get_der()

void tor_x509_cert_get_der ( const tor_x509_cert_t *  cert,
const uint8_t **  encoded_out,
size_t *  size_out 
)

Set *encoded_out and *size_out to cert's encoded DER representation and length, respectively.

◆ tor_x509_cert_get_id_digests()

const common_digests_t* tor_x509_cert_get_id_digests ( const tor_x509_cert_t *  cert)

Return a set of digests for the public key in cert, or NULL if this cert's public key is not one we know how to take the digest of.
