NAME

Crypt::Perl::RSA::PKCS1_v1_5 - PKCS1 v1.5 signature padding

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',
);
