Adapt mbedtls support for compatibility with v3, while maintaining compatibility with v2. Notice v3 has removed the ability to encrypt with pubkey and decrypt with privkey. Openssl still has it, atm with v3 these fall back to encrypt with privkey and decrypt with pubkey. > The RSA module no longer supports private-key operations with the > public key or vice versa. As a consequence, RSA operation functions > no longer have a mode parameter. If you were calling RSA operations > with the normal mode (public key for verification or encryption, > private key for signature or decryption), remove the > MBEDTLS_MODE_PUBLIC or MBEDTLS_MODE_PRIVATE argument. If you were > calling RSA operations with the wrong mode, which rarely makes sense >from a security perspective, this is no longer supported.
