Description : Perl module implementing the RSA public-key cryptosystem
Crypt::RSA is a pure-perl, cleanroom implementation of the RSA
public-key cryptosystem. It uses Math::Pari(3), a perl interface to the
blazingly fast PARI library, for big integer arithmetic and number
Crypt::RSA provides arbitrary size key-pair generation, plaintext-aware
encryption (OAEP) and digital signatures with appendix (PSS). For
compatibility with SSLv3, RSAREF2, PGP and other applications that
follow the PKCS #1 v1.5 standard, it also provides PKCS #1 v1.5
encryption and signatures.
Crypt::RSA is structured as bundle of modules that encapsulate different
parts of the RSA cryptosystem. The RSA algorithm is implemented in
Crypt::RSA::Primitives(3). Encryption schemes, located under
Crypt::RSA::ES, and signature schemes, located under Crypt::RSA::SS, use
the RSA algorithm to build encryption/signature schemes that employ
secure padding. (See the note on Security of Padding Schemes.)
The key generation engine and other functions that work on both
components of the key-pair are encapsulated in Crypt::RSA::Key(3).
Crypt::RSA::Key::Public(3) & Crypt::RSA::Key::Private(3) provide
mechanisms for storage & retrival of keys from disk, decoding & encoding
of keys in certain formats, and secure representation of keys in memory.
Finally, the Crypt::RSA module provides a convenient, DWIM wrapper
around the rest of the modules in the bundle.
