The pam_rsa PAM-module (also known as "poor man's smartcard") is for local PAM-authentication with RSA keypairs. It cannot be used for authenticating to PAM-services on remote hosts. The basic idea is that RSA private keys are stored on removable and easily portable medias like USB memory sticks. This package provides the pam-rsa.so module for PAM. .
