i2d functions on the PC

[jon brace]

I have successfully installed openssl on Windows 2000.  I am now testing programs to generate private and pub keys, write them to a file, and then using the private key to sign a text file.  This code has been taken from UNIX Solaris OS, where it works fine.   I have tried taking the public key, the text to be signed, and the signature file from the UNIX platform, and using the PC decryption program to check that the signature file matches the decrypted signature.  Although they do match on the UNIX platform, on the PC they do not.    It may have something to do with writing the keys and signature to file using the i2d_.. functions.  Has anyone any ideas?   Jon Brace
