Function Details

gen_params(curve)

Factory function that generates EC parameters and instantiates a EC object from the output.

Parameters:

curve - This is the OpenSSL nid of the curve to use.

load_key(file, callback=<function passphrase_callback at 0x83b2a04>)

Factory function that instantiates a EC object.

Parameters:

file - Names the file that contains the PEM representation of the EC key pair.
callback - Python callback object that will be invoked if the EC key pair is passphrase-protected.

load_key_bio(bio, callback=<function passphrase_callback at 0x83b2a04>)

Factory function that instantiates a EC object.

Parameters:

bio - M2Crypto.BIO object that contains the PEM representation of the EC key pair.
callback - Python callback object that will be invoked if the EC key pair is passphrase-protected.

load_pub_key(file)

Load an EC public key from file.

Parameters:

file (string) - Name of file containing EC public key in PEM format.

Returns: M2Crypto.EC.EC_pub

M2Crypto.EC.EC_pub object.

load_pub_key_bio(bio)

Load an EC public key from an M2Crypto.BIO.BIO object.

Parameters:

bio (M2Crypto.BIO.BIO) - M2Crypto.BIO.BIO object containing EC public key in PEM format.

Returns: M2Crypto.EC.EC_pub

M2Crypto.EC.EC_pub object.
