Examples and HowTos for BouncyCastle and Java Cryptography Extension (JCE)

See class "/src/main/java/de/soderer/utilities/crypto/CryptographicUtilities.java" for handling of symmetric and asymmetric keys.

Asymmetric Encryption

See classes "/src/main/java/de/soderer/utilities/crypto/Asymmetric*Worker.java" for asymmetric enryption/decryption and signing/verification of data.

Symmetric Encryption

See classes "/src/main/java/de/soderer/utilities/crypto/Symmetric*Worker.java" for symmetric enryption/decryption of data.
