Hi guys, I'm currently writing a little test application using RSA's JSAFE libraries (java version of BSAFE), and I'm generating my keys using openssl, however I cannot get a signature to verify successfully. An example program (with hard coded bytes for the private key) using an rsa algorithm works correctly.
I was comparing the differences of the supplied private key and the private key i generated in openssl and there appear to be a few small differences. In the rsa example program the modulus, private exponent, prime1, prime2, exponent 1 are all one byte shorter in the example than what openssl generates. The difference appears to be a beginning 0x00 byte. So I removed the beginning byte and tried to verify the signature again but it failed. The openssl command I used to create the my private key was: `openssl genrsa -out private_key.pem -f4 768` Then I got the values, `openssl rsa -in private_key.pem -text -noout` and converted them to a byte array. I have pasted the supplied hard coded private key (which is 512bit, the one I have tested is 768bit but it shouldn't make a difference) to a paste bin here: http://pastebin.com/f2900d840 The program generates the public key from the modulus/public exponent but for some reason only the hard coded private key verifys for me. I assume both formats are the same standard RSA key? If anyone has any ideas as to why its failing to verify I'd greatly appreciate it, Cheers, ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]
