Cryptographic Libraries for JavaScript, Python, C# and Java

• Cryptography in JavaScript
  • ECDSA, elliptic.js, js-sha3.js
• Cryptography libraries in Python
  • ECDSA, eth_keys
• C# and .NET cryptography
  • Bouncy Castle .NET, Nethereum
• Java cryptography
  • JCA, Bouncy Castle, Web3j
• C and C++ cryptography
  • Crypto++, OpenSSL bindings, Nettle, libgcrypt

TODO:

• OpenSSL - https://en.wikipedia.org/wiki/OpenSSL
• LibSodium
• Crypto++
• Lingcrypt - https://en.wikipedia.org/wiki/Libgcrypt
• Bouncy Castle
• Nettle - https://git.lysator.liu.se/nettle/nettle
• Botan - https://botan.randombit.net
• Others...

Summary

• JavaScript and Python provide simple cryptography libraries

  • Hashes, ECC, ECDSA, AES, and many more

• Cryptography is C# is heavy

  • Use Bouncy Castle .NET for general crypto
  • Or Nethereum for simplified secp256k1

• Cryptography in Java is heavy

  • JCA and Bouncy Castle are hard to use
  • Web3j is simplifies library for secp256k1
