Crypt::RSA::Simple - Encrypts/decrypts text with RSA keys

use Crypt::RSA::Simple;

my $crypt = Crypt::RSA::Simple->new(
  key_dir     => '/home/user/keys',
  key_size    => 2048,
  private_key => 'secure_key.priv',
  public_key  => 'secure_key.pub',
);

$crypt->generate()

Or it can be fed with method arguments:

my $crypt = Crypt::RSA::Simple->new();

$crypt->generate(
  '/home/user/keys',
  2048,
  'secure_key.priv',
  'secure_key.pub'
);

Private and public keys can be set with their getter/setter methods as well as the key_dir and key_size:

my $crypt->private_key( '/home/user/keys/secret.priv' );
my $crypt->public_key( '/home/user/keys/secret.pub' );

my $crypted   = $crypt->encrypt( 'text to crypt' );
my $encrypted = $crypt->decrypt( $crypted );

Or keys can be used with the crypt and decrypt methods as their arguments as well:

my $decrypted = $crypt->decrypt(
  'encrypted text',
  '/home/user/keys/secret.priv'
);

Class methods and instance methods are both supported:

Crypt::RSA::Simple->encrypt( 'text', '/home/user/keys/secret.pub' );

Crypt::RSA::Simple is just a tiny but flexible wrapper on the top of the Crypt::OpenSSL::RSA library. It encrypts and decrypts any text, and it can generate RSA keys if necessary.

This tool does not give any new features to the original module, rather it wraps it into an easy-to-use form. It offers an elegant, pure Perl OO interface.

It uses MIME::Base64 to encode/decode the crypted text, makes it easier to store it on a drive e.g. in a file.

new:

Creates a new Crypt::RSA::Simple object instance

Arguments:

key_dir: Path to the key directory (String)

key_size: Key size for key generation (Integer)

private_key: Name of the key (String)

public_key: Name of the key (String)

All parameters can be set with getter/setter methods

private_key:

Getter/setter method for the private key

public_key:

Getter/setter method for the public key

key_dir:

Getter/setter method for the key directory

key_size:

Getter/setter method for the key size

generate:

Method for private and public key generation

Arguments:

key_dir: Path to the key directory (String)

key_size: Key size for key generation (Integer)

private_key: Name of the key (String)

public_key: Name of the key (String)

This method generates a key pair into the key_dir to encrypt and decrypt with. If it is called without arguments it uses the default values.

encrypt

Method for text encrytion

Arguments:

text: Text to be encrypted (String)

public_key: Public key for encryption (String)

decrypt

Method for decrypting ecrypted text

Arguments:

text: Text to be decrypted (String)

private_key: Private key for encryption (String)
