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.
