Function Documentation

struct tls_cipher_suite* tls_get_cipher_suite

(

u16

suite

)

[read]

Get TLS cipher suite.

Parameters:

suite

Cipher suite identifier

Returns:

Pointer to the cipher data or NULL if not found

Definition at line 93 of file tlsv1_common.c.

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:

	buf	ASN.1 DER encoded certificate
	len	Length of the buffer
	pk	Buffer 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().
