Bouncy Castle is a cryptography API providing various cryptography, encryption, and security protocols. There are fairly similar libraries in both C# and Java that implement the API. Additionally, Bouncy Castle provides a JCE-compliant crypto provider for Java.

  • Generation and parsing of PKCS#12 files.
  • X.509: Generators and parsers for V1 and V3 certificates, V2 CRLs and attribute certificates.
  • PBE algorithms supported by PBEUtil: PBEwithMD2andDES-CBC, PBEwithMD2andRC2-CBC, PBEwithMD5andDES-CBC, PBEwithMD5andRC2-CBC, PBEwithSHA1andDES-CBC, PBEwithSHA1andRC2-CBC, PBEwithSHA-1and128bitRC4, PBEwithSHA-1and40bitRC4, PBEwithSHA-1and3-keyDESEDE-CBC, PBEwithSHA-1and2-keyDESEDE-CBC, PBEwithSHA-1and128bitRC2-CBC, PBEwithSHA-1and40bitRC2-CBC, PBEwithHmacSHA-1, PBEwithHmacSHA-224, PBEwithHmacSHA-256, PBEwithHmacRIPEMD128, PBEwithHmacRIPEMD160, and PBEwithHmacRIPEMD256.
  • Signature algorithms supported by SignerUtilities: MD2withRSA, MD4withRSA, MD5withRSA, RIPEMD128withRSA, RIPEMD160withRSA, RIPEMD256withRSA, SHA-1withRSA, SHA-224withRSA, SHA-256withRSAandMGF1, SHA-384withRSAandMGF1, SHA-512withRSAandMGF1, SHA-1withDSA, and SHA-1withECDSA.
  • Symmetric key algorithms: AES, Blowfish, Camellia, CAST5, CAST6, DESede, DES, GOST28147, HC-128, HC-256, IDEA, NaccacheStern, RC2, RC4, RC5-32, RC5-64, RC6, Rijndael, Serpent, Skipjack, TEA/XTEA, Twofish, and VMPC.
  • Symmetric key modes: CBC, CFB, CTS, GOFB, OFB, OpenPGPCFB, and SIC (or CTR).
  • Symmetric key paddings: ISO10126d2, ISO7816d4, PKCS#5/7, TBC, X.923, and Zero Byte.
  • Asymmetric key algorithms: RSA (with blinding), ElGamal, DSA, ECDSA.
  • Asymmetric key paddings/encodings: ISO9796d1, OAEP, and PKCS#1.
  • Digests: GOST3411, MD2, MD4, MD5, RIPEMD128, RIPEMD160, RIPEMD256, RIPEMD320, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, Tiger, and Whirlpool.

  • Key Agreement: Diffie-Hellman and EC-DH.
  • Macs: CBCBlockCipher, CFBBlockCipher, GOST28147, HMac, and ISO9797 Alg. 3.
  • PBE generators: PKCS#12, and PKCS#5 - schemes 1 and 2.
  • OpenPGP (RFC 2440)
  • Cryptographic Message Syntax (CMS, RFC 3852), including streaming API.
  • Online Certificate Status Protocol (OCSP, RFC 2560).
  • Time Stamp Protocol (TSP, RFC 3161).
  • TLS/SSL Client with support for client side authentication.
