Packages

  1. cipher: It includes both symmetric(AES) and asymmetric(RSA) key encryption.

  2. signature: It includes signature algorithms like HMAC, RSA etc.

  3. hash: It has common hash functions including SHA1 and SHA256.

  4. Keystore: It implements key store and key generation for common cryptographic algorithms.

cipher

AES

It support the following modes of operations

  1. CBC (https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#Cipher_block_chaining_(CBC))
  2. CTR (https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#Counter_(CTR))
  3. CFB (https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#Cipher_feedback_(CFB))

and the following padding schemes

  1. PKCS5 (https://en.wikipedia.org/wiki/Padding_(cryptography)#PKCS#5_and_PKCS#7)
  2. PKCS7

RSA

It supports the following encryption schemes

  1. PKCS1 (https://datatracker.ietf.org/doc/html/rfc3447)
  2. OAEP (https://en.wikipedia.org/wiki/Optimal_asymmetric_encryption_padding)

signature

RSA

It supports the following signature schemes

  1. PKCS1 (https://en.wikipedia.org/wiki/PKCS_1)
  2. PSS (https://en.wikipedia.org/wiki/Probabilistic_signature_scheme)

Notes

  1. It uses pem format for all public key infrastructure.
