Chilkat Crypt C Library

Chilkat Crypt C Library is a powerful software component designed  for encrypting and decrypting both strings and binary data. Provides BZIP2 compression for both strings and binary data.

Major Features:

1. Symmetric Encryption: AES, Blowfish, Twofish, RC2, ARC4, DES, 3DES, PBES1, PBES2.
2. Hash Algorithms: SHA-1, SHA256, SHA384, SHA512, MD2, MD4, MD5, HAVAL.
3. Hash Algorithms: RIPEMD128, RIPEMD160, RIPEMD256, RIPEMD320.
4. Encoding: Base64, hex, quoted-printable, URL-encoding.
5. HMAC with any supported hash algorithm: HMAC-MD5, HMAC-SHA1, etc.
6. Password-based Key Derivation Functions: PBKDF1, PBKDF2
7. PKCS7 -- P7S and P7M creation, decryption, verification.
8. Public key encryption/decryption with digital certificates.
9. Digital signature creation/verification with digital certificates.
10. Bzip2 in-memory compression.
11. Encrypt / decrypt strings or byte data.
12. Return encrypted data as Base64, quoted-printable, or hex-encoded strings.
13. Hash strings or binary data using SHA1, MD2, MD5, HAVAL, SHA384, or SHA512.
14. Public-key encryption with digital certificates.
15. Create and verify digital signatures.
16. Pre-convert Unicode strings to ANSI (single-byte/char) before encrypting.
17. Pre-convert Unicode strings to any charset before encrypting, compressing, or hashing.
18. Base64 encode strings or byte data.
19. Hex-encode encode strings or byte data.
20. Compress strings or byte data with the BZIP2 compression algorithm.
21. Implements FIPS81 padding scheme for AES.
22. Up to 256-bit encryption is supported.
23. Set binary secret-key directly for symmetric encryption algorithms.
24. Initialization vectors.
25. CBC (Cipher Block Chaining) Mode
26. ECB (Electronic Cookbook) Mode
27. Random byte data generation.
28. Streaming hashing (pass data to hashing functions in chunks).
29. Streaming encryption (pass data to encryption functions in chunks).
