libcrypt-openssl-bignum-perl 0.07-1 (amd64 binary) in ubuntu zesty

 Presently, many though not all of the arithmetic operations that OpenSSL
 provides are exposed to Perl via Crypt::OpenSSL::Bignum. In addition, this
 module can be used to provide access to bignum values produced by other
 OpenSSL modules, such as key parameters from Crypt::OpenSSL::RSA.
