Package perl-Crypt-RSA: Information

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 theoretic
computations.

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.
