Hi,
I've been working on an old source that, compiled, will give you the ability to
sign and verify the signature. It can sign and include data in the signature.
Simple usage:
usage: sign args
-in file - Input file
-out file - File where to write to
-cert file - Certificate file
-keyfile file - Sign key file
-key - Password protecting the private key
-nd - No detach signature
-verbose - Verbose printing
While Verify tool usage is:
usage: verify args
-in file - Input file
-out file - Output file
-data file - File containing signed data
-cf file - CA's certificate file
-cd certsdir - CAs' certificates directory
-print_data - Print Signed Data to outfile
-no_chain - Verifiy Just signature.
-verbose - Verbose output
You can download it from:
ftp://ftp.openca.org/pub/modules/OpenCA-SV-0.5.98.tar.gz
Hope this will solve your problems... :-D
