Thanks all for replying to my thread. Ya to be more specific, I want to sign and verify Word Document File and using command line will be fine for now. For this I am using SHA-1 to generate hash of the input message, than I want to use RSA for signing this message digest, which finally will be appended to Word Document containing the input message. So now the problem I am facing here is using OpenSSL rsautl OpenSSL> rsautl -sign -in file1.doc -inkey private.pem -out sig Loading 'screen' into random state - done RSA operation error 660:error:0406C06E:rsa routines: RSA_padding_add_PKCS1_type_1:data too large for key size: .\crypto\rsa\rsa_pk1.c:73: error in rsautl What should I do to fix this error so that it supports long word document files too?
