Crypt::RSA::Key::PrivaUser)Contributed Perl DocumenCrypt::RSA::Key::Private(3)NAMECrypt::RSA::Key::Private-- RSA Private Key Management.
SYNOPSIS
$key = new Crypt::RSA::Key::Private (
Identity => 'Lord Banquo <banquo@lochaber.com>',
Password => 'The earth hath bubbles',
);
$key->hide();
$key->write( Filename => 'rsakeys/banquo.private' );
$akey = new Crypt::RSA::Key::Private (
Filename => 'rsakeys/banquo.private'
);
$akey->reveal ( Password => 'The earth hath bubbles' );
DESCRIPTIONCrypt::RSA::Key::Private provides basic private key management func-
tionality for Crypt::RSA private keys. Following methods are available:
new()
The constructor. Takes a hash, usually with two arguments: "File-
name" and "Password". "Filename" indicates a file from which the
private key should be read. More often than not, private keys are
kept encrypted with a symmetric cipher and MUST be decrypted before
use. When a "Password" argument is provided, the key is also
decrypted before it is returned by "new()". Here's a complete list
of arguments accepted by "new()" (all of which are optional):
Identity
A string identifying the owner of the key. Canonically, a name
and email address.
Filename
Name of the file that contains the private key.
Password
Password with which the private key is encrypted, or should be
encrypted (in case of a new key).
Cipher
Name of the symmetric cipher in which the private key is
encrypted (or should be encrypted). The default is "Blowfish"
and possible values include DES, IDEA, Twofish and other
ciphers supported by Crypt::CBC.
reveal()
If the key is not decrypted at "new()", it can be decrypted by
calling "reveal()" with a "Password" argument.
hide()
"hide()" causes the key to be encrypted by the chosen symmetric
cipher and password.
write()
Causes the key to be written to a disk file specified by the "File-
name" argument. "write()" will call "hide()" before writing the key
to disk. If you wish to store the key in plain, don't specify a
password at "new()".
read()
Causes the key to be read from a disk file specified by "Filename"
into the object. If "Password" is provided, the method automati-
cally calls reveal() to decrypt the key.
serialize()
Creates a Data::Dumper(3) serialization of the private key and
returns the string representation.
deserialize()
Accepts a serialized key under the "String" parameter and coverts
it into the perl representation stored in the object.
"check()"
Check the consistency of the key. If the key checks out, it sets
$self->{Checked} = 1. Returns undef on failure.
