Crypt::Perl::RSA::Generate - RSA key generation
use Crypt::Perl::RSA::Generate ();
#$prkey is a Crypt::Perl::RSA::PrivateKey instance.
my $prkey = Crypt::Perl::RSA::Generate::create(2048);
Unfortunately, this is quite slow in Perl—too slow, in fact, if you
don’t have either Math::BigInt::GMP or Math::BigInt::Pari. The logic
here will still run under pure Perl, but it’ll take too long to be
The current Math::ProvablePrime backend is slated to be replaced
with Math::Prime::Util; once that happens, pure-Perl operation should be
much more feasible.
- Crypt::OpenSSL::RSA - probably the fastest way to generate RSA keys in
perl. (It relies on XS, so this project can’t use it.)
- Use the "openssl" binary OpenSSL <http://openssl.org>
directly, e.g., "my $rsa_pem = qx/openssl genrsa/". Most *NIX
systems can do this.
NOTE: As of December 2016, Crypt::PK::RSA is NOT suitable for key
generation because it can only generate keys with up to a 512-bit
