There is a Debian bug report requesting SHA-256/512 password hash support, but currently nothing has been done. How can I generate a hashed password for /etc/shadow? To help you get your OpenSSL hash signing up and running, we have included a sample code in this topic. How can The technical answer is actually "no, because SHA-256 with RSA-2048 Encryption is not a certificate hashing algorithm.However, SHA-256 is a perfectly good secure hashing … Use SHA256 for FIPS 140-2. Then you can submit your request by clicking on the compute hash button to generate the HMAC authentication code for you. Comments (5) cmd powershell windows.
