Detailed Description

TLSv1 common definitions.

Function Documentation

const struct tls_cipher_suite* tls_get_cipher_suite ( u16  suite)

Get TLS cipher suite.

Parameters
suiteCipher suite identifier
Returns
Pointer to the cipher data or NULL if not found
int tls_parse_cert ( const u8 *  buf,
size_t  len,
struct crypto_public_key **  pk 
)

Parse DER encoded X.509 certificate and get public key.

Parameters
bufASN.1 DER encoded certificate
lenLength of the buffer
pkBuffer for returning the allocated public key
Returns
0 on success, -1 on failure

This functions parses an ASN.1 DER encoded X.509 certificate and retrieves the public key from it. The caller is responsible for freeing the public key by calling crypto_public_key_free().
