Text Library: RSA Public-key Encryption
This library has 21 classes.
ECF: public-key-encryption.ecf
Extends Colin LeMahieu's arbitrary precision integer library to conform to some RSA standards. The most important is the ability to read key-pairs conforming to the X509 PKCS1 standard. The top level class to access these facilities is EL_MODULE_X509.
The private key reader however uses a non-standard encryption scheme. It assumes the file is encrypted using the Eiffel-Loop utility contained in el_toolkit.
