3.8.10 What is RSAREF?

  RSAREF is a collection of cryptographic routines in portable C source code, available at no charge from RSA Laboratories, a division of RSA Data Security, Inc. It includes RSA, MD2, MD5, and DES; Diffie-Hellman key exchange will be included in a forthcoming version. It includes both low-level subroutines, such as modular exponentiation, and high-level cryptographic functions, such as verification of digital signatures. The arithmetic routines can handle multiple-precision integers, and the RSA algorithm routines can handle variable key sizes. RSAREF is fully compatible with the PEM and PKCS standards.

RSAREF is available to citizens of the U.S. or Canada and to permanent residents of the U.S. It can be used in personal, non-commercial applications but cannot be used commercially or sent outside the U.S. and Canada. The RSAREF license contains more details on the usage allowed and disallowed. RSAREF is available on the Internet by sending e-mail to or by anonymous ftp to .
