- * Revision 1.4  2000/07/01 11:22:22  mdw
- * Remove bad type name `rsa_param'.

- * Revision 1.2  2000/06/17 12:07:19  mdw
- * Fix a bug in argument validation.  Force %$p > q$% in output.  Use
- * %$\lambda(n) = \lcm(p - 1, q - 1)$% rather than the more traditional
- * %$\phi(n) = (p - 1)(q - 1)$% when computing the decryption exponent.
