J has been able to encrypt/decrypt (verify/sign) rsa signatures for some time, with special code.
http://www.jsoftware.com/jwiki/PascalJasmin/RSA%20native%20and%20openssl%20control includes code to generate and retrieve key parameters by spawning openssl commanline tools. The first line of script is the openssl path. on 32bit system, verify works, but RSAsign has a limit error at 960 bitlength. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
