This class provides methods to
crypt() routine with
randomly chosen salt.
The current version of LibWeb::Crypt is available at
http://libweb.sourceforge.net
Several LibWeb applications (LEAPs) have be written, released and are available at
http://leaps.sourceforge.net
encrypt_cipher()
Params:
-data=>, -key=>, -algorithm=>, -format=>
Pre:
-data is the data to be encrypted as cipher,
-key is the private key such the same key is needed to decrypt the
cipher (sorry, I do not have a rigorous definition for that right
now),
-algorithm must be 'Crypt::Blowfish', 'Crypt::DES' or
'Crypt::IDEA',
-format is the format of the cipher, which must be either 'binary'
or 'hex'.
Post:
-data and return the cipher.
Note: this makes use of the Crypt::CBC module and therefore can accept data of arbitrary length.
decrypt_cipher()
Params:
-cipher=>, -key=>, -algorithm=>, -format=>
Pre:
-cipher is the cipher to be decrypted,
-key is the private key such that it is the same key used to
encrypt the original data of -cipher (sorry, I do not have a
rigorous definition for that right now),
-algorithm must be 'Crypt::Blowfish', 'Crypt::DES' or 'Crypt::IDEA'
and it must match the algorithm used when preparing the cipher,
-format is the format of the cipher, which must be either 'binary'
or 'hex'.
Post:
-cipher and return the original data.
encrypt_password()
Usage:
my $encrypted_password =
$crypt->encrypt_password($password_in_plain_text);
Encrypts the parameter (usually a password) and returns a 13-character
long string using the perl's crypt() routine and randomly chosen salt.
the Digest::HMAC manpage, the Digest::SHA1 manpage, the Digest::MD5 manpage, the Crypt::CBC manpage, the Crypt::Blowfish manpage, the Crypt::DES manpage, the Crypt::IDEA manpage, the LibWeb::Admin manpage, the LibWeb::Digest manpage, the LibWeb::Session manpage.
