I think you've been given the private key, so you just need to somehow combine the bits you've been given into the form that OpenSSL wants. Probably (and this is the bit that's beyond me) you need to produce a group and a public key (both of which are public parts of the key), and presumably these are the first numbers you gave. Then, you need to use the private key and the random number to form the ECDSA signature of the file. ECDSA with SHA1 requires 160 bits of random data, which is exactly what you've been given so that matches up. (I don't see a way to provide the random number to any of the OpenSSL functions, so perhaps some hacking will be needed for that part.) ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
