NAME

Crypt::ECDSA::PEM -- ECDSA PEM file management for elliptic key DSA cryptography

DESCRIPTION

These are for use with Crypt::ECDSA, a Math::GMPz based cryptography module.

METHODS

new

Constructor.  Takes the following named pair arguments:

filename =>  $file_name

Open and parse a PEM key file at initialization of the object.

password => $passwd

Use $passwd as a key to and encrypted PEM file.

read_PEM

$pem->read_PEM( filename => $filename, password => $password );

Read and parse a PEM file.  The password is optional.

read_PEM_fh

$pem->read_PEM_fh( filename => $fname );

Read from an open file handle.  Otherwise like read_PEM().

write_PEM

$pem->write_PEM( filename => $outfile, private => 1, password => $pwrd );

Write a PEM file.  The private parameter indicates to write out the 
private key.  Otherwise the public key only is wriiten to the file.
The password is for encryption if desired.

key_to_private_pem

my $pem_text = $pem->key_to_private_pem( $key, $password );
print $pem_text;

Create and return a PEM file containing the pirvate and public keys as 
a scalar.  The second, password parameter is optional.

TODO

Password protection with encrypted private key PEM files requires that the Rijndael
module be used, so far.   Other cipher support to be added.
