newSHA

Construct a Digest::SHA object of class $classname for an algorithm number: 1, 224, 256, 384, 512, 512224 or 512256. Any other number returns undef.

Digest::SHA->new is the usual way in; it strips a name such as "SHA-256" down to its digits and calls $class->newSHA($alg).

Synopsis

my $sha = Digest::SHA->newSHA(256);
my $sub = Digest::SHA::newSHA("My::Digest", 1);   # blessed into My::Digest
