I need to create a SHA256 signature using OpenSSL ?
I tried:
openssl sha256 -sha256 -binary -sign (providing my priv key & contents)
But, I get the following error : openssl:Error: 'sha256' is an invalid command.
sha1 works fine, but I thought sha256 was supported as well.
OpenSSL uses the command ‘dgst‘ to calculate various digests (including SHA-256). The command also allows you to sign a digest (using a private key) and verify a signature (using a public key).
