improve RSA functionality

Jira Information

Original Issue:	ZF-12472
Issue Type:	Improvement
Reporter:	Ad Jails
Created:	11/21/12
Assignee:	Pádraic Brady
Components:	Zend_Crypt

Description

This would break BC but phpseclib's Crypt_RSA seems much more feature packed then the RSA implementation in ZF. PEAR's own Crypt_RSA has deprecated itself in favor of phpseclib's implementation.

Among other features phpseclib's Crypt_RSA supports... more key formats, key conversion, PSS signing and OAEP encryption.

We will not add any new features or functionality for ZF1.
Please look at ZF2 there we have a new component for this. Thanks!
