OpenSSL currently imposes a limit of 16K bits, and in my experience anything much over 4K bits becomes unusably slow on available hardware. I think OpenSSL could be easily tweaked to allow more if you want to wait long enough, since the underlying bignum code has no practical limit, but I don't know about anything else you might interoperate with. ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
