SYNOPSIS

    my $digest = Digest::SHA::sha256('This is my message.');

    my $sig = Crypt::Perl::RSA::PKCS1_v1_5::encode(
        $digest,
        'sha256',   #digest OID; see below
        2048,       #the bit length of the key’s modulus
    );

    #This value should match $digest.
    my $digest_dec = Crypt::Perl::RSA::PKCS1_v1_5::decode(
        $sig,
        'sha256',
    );

LIST OF DIGEST OIDs

• sha512
• sha384
• sha256

The following are considered too weak for good security now; they’re included for historical interest.

• sha1
