I've read RSA (for example) can be used to encrypt file using private key and decrypt using public key. I distribute some files to clients and I don't want them to modify my files. Of course, file modification check can be done using digital signature or etc. But I want to use RSA public key system to do this work. Simply using public key for decryption and private key for encryption seems not working. How can I use Crypto++ to do such a thing? Thanks in advance.
