You have Alt::Crypt::RSA::BigInt installed (not Alt::Crypt::RSA)? Also install Math::BigInt::GMP.

One rather crude way to check is to do man Crypt::RSA and check the REPORTING BUGS section. If it has a third paragraph talking about segmentation faults and Math::Pari, then you've got the original Math::Pari version. Here's a more complicated but better one command line method:

perl -E 'use Crypt::RSA::Key; my($pari,$big) = ($Math::Pari::VERSION, +$Math::BigInt::VERSION); my $lib = Math::BigInt->config()->{lib} if $ +big; printf "Using %s\n", $pari ? "Pari $pari" : $big ? "BigInt with +$lib" : "???";'

With Crypt::RSA installed it shows Using Pari 2.01080900 where with Alt::Crypt::RSA::BigInt it shows Using BigInt with Math::BigInt::GMP

/dev/urandom shouldn't be hanging. Crypt::Random reads from /dev/random which can block waiting for more entropy. Alt::Crypt::RSA::BigInt version 0.06 (April 2017) should just read about 256 bytes at the start, as it uses an ISAAC CSPRNG after that.

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
