EC_KEY* d2i_ECParameters	(	EC_KEY **	key,
		const unsigned char **	in,
		long	len
	)

Decodes ec parameter from a memory buffer.

Parameters

key	a pointer to a EC_KEY object which should be used (or NULL)
in	pointer to memory with the DER encoded ec parameters
len	length of the DER encoded ec parameters

Returns

a EC_KEY object with the decoded parameters or NULL if an error occurred.

EC_KEY* d2i_ECPrivateKey	(	EC_KEY **	key,
		const unsigned char **	in,
		long	len
	)

Decodes a private key from a memory buffer.

Parameters

key	a pointer to a EC_KEY object which should be used (or NULL)
in	pointer to memory with the DER encoded private key
len	length of the DER encoded private key

Returns

the decoded private key or NULL if an error occurred.

int i2d_ECParameters	(	EC_KEY *	key,
		unsigned char **	out
	)

Encodes ec parameter and stores the result in a buffer.

Parameters

key	the EC_KEY object with ec paramters to encode
out	the buffer for the result (if NULL the function returns number of bytes needed).

Returns

1 on success and 0 if an error occurred.

int i2d_ECPrivateKey	(	EC_KEY *	key,
		unsigned char **	out
	)

Encodes a private key object and stores the result in a buffer.

Parameters

key	the EC_KEY object to encode
out	the buffer for the result (if NULL the function returns number of bytes needed).

Returns

1 on success and 0 if an error occurred.

Definition at line 1224 of file ec_asn1.c.

int i2o_ECPublicKey	(	EC_KEY *	key,
		unsigned char **	out
	)

Encodes a ec public key in an octet string.

Parameters

key	the EC_KEY object with the public key
out	the buffer for the result (if NULL the function returns number of bytes needed).

Returns

1 on success and 0 if an error occurred

Definition at line 1405 of file ec_asn1.c.

EC_KEY* o2i_ECPublicKey	(	EC_KEY **	key,
		const unsigned char **	in,
		long	len
	)

Decodes a ec public key from a octet string.

Parameters

key	a pointer to a EC_KEY object which should be used
in	memory buffer with the encoded public key
len	length of the encoded public key

Returns

EC_KEY object with decoded public key or NULL if an error occurred.
