I am working on a project that requires encrypting messages with different ciphers. I am looking for the following ciphers:

  • LEA,
  • Hill cipher,
  • Affine cipher,
  • Elliptic Curve Cryptography.

In the past, I used AES from openssl UNIX utility which is pretty much standardized. I found some implementations on github which may be faulty as there is no associated confidence with them. Since the whole project actually relies on this step, it is desirable that I use the most standardized implementations of these ciphers.

I might also implement them on my own but there is no use reinventing the wheel. I feel there exist standardized ones out there. I searched at NIST website too but to no avail.

Please let me know if you know of some standardized implementations that most of the community uses. Apologies for sounding like a newbie. I am quite new to the interesting world of cryptography. Thanks a lot!

  • $\begingroup$ Present and Clefia are ISO standards . You should google it. You can find present implementation in lightweightcrypto.org/present $\endgroup$ – hardyrama Dec 18 '19 at 1:06
  • $\begingroup$ @hardyrama Thanks a lot. That's exactly what I wanted. If someone could guide me to other ciphers' implementation too, that would be great. $\endgroup$ – Madhur Panwar Dec 18 '19 at 7:42
