DO NOT USE A RANDOM GITHUB REPO FOR CRYPTOGRAPHY - this was made only for my own education and is probably not secure!

Java-Cryptography-Best-Practices

As cybersecurity gets more relevent every day and examples of secure Implementations are often hard to come by -
this Repo aims to get some Best-Practice-Implementations of common and secure Cryptography Algorithms in Java out there.

Only well-known / secure Libraries or the Standard-Libraries are used.
I aim to choose secure Paremters for the Cryptographic Functions and also explain them in the comments.

Currently the following Crypto-Algo-Best-Practices are finished and to my best knowledge secure to use:

Asymmetric-Encryption:

• RSAAsymmetricEncryption.java using "RSA-4096 with OAEP-SHA512MGF1Padding"

Symmetric-Encryption:

• ChaCha20-Poly1305 Authenticated Encryption using 256bit Keys

Digital-Signatures:

• ECDSA Signatures using Standard Java11 Elliptic Curves - get supported curves by running CryptoHelper.ShowSupportedECCurves

Secure Hash-Functions

• Argon2iHashSecure using Argon2i and explaining all parameters

General Hash-Functions

• SHA512Hash
• SHA256Hash

As you may have noticed this repo is work in Progress.

Several more Implementation will come next month
