Function Documentation

fr_tls_utils_asn1time_to_epoch()

int fr_tls_utils_asn1time_to_epoch	(	time_t *	out,
		ASN1_TIME const *	asn1
	)

Convert OpenSSL's ASN1_TIME to an epoch time.

Parameters

[out]	out	Where to write the time_t.
[in]	asn1	The ASN1_TIME to convert.

Returns

• 0 success.
• -1 on failure.

fr_tls_utils_keyblock_size_get()

int fr_tls_utils_keyblock_size_get	(	request_t *	request,
		SSL *	ssl
	)

Returns the OpenSSL keyblock size.

this function shamelessly stolen from from hostap:src/crypto/tls_openssl.c:openssl_get_keyblock_size()

Parameters

[in]	request	The current request.
[in]	ssl	The current SSL session.

Returns

• -1 problem with the session.
• >=0 length of the block.

fr_tls_utils_x509_pkey_type()

char const * fr_tls_utils_x509_pkey_type

(

X509 *

cert

)

Returns a friendly identifier for the public key type of a certificate.

Parameters

[in]

cert

The X509 cert to return the type of.

Returns

the type string.

fr_utils_get_private_key_password()

int fr_utils_get_private_key_password	(	char *	buf,
		int	size,
		UNUSED int	rwflag,
		void *	u
	)

Return the static private key password we have configured.

Note

This is used as a callback to OpenSSL's PEM_read_PrivateKey function.

Parameters

[out]	buf	Where to write the password to.
[in]	size	The length of buf.
[in]	rwflag	0 if password used for decryption. 1 if password used for encryption.
[in]	u	The static password.

Returns

• 0 on error.
• >0 on success (the length of the password).
