1.1.1

• ✔️ Fixed issues in XmlDoc
• ➕ Removed all maximum bit limits
• ❌ Removed redundant enum aliases from CrcOptions enums
• ➕ Added more CRC config presets (now there are almost 90 in total)
• ⭕ Redesigned CrcConfig to significantly improve performance 🔸 BREAKING CHANGE
• ➕ Added IChecksumResult interface
• ➕ Added various utilities to CryptoUtils class
• ✔️ Fixed issue where CRC-16/XMODEM was incorrect for extension methods
• ➕ Added <Type>.Create() methods for ChecksumAlgorithm types
• ➕ Added explizit operators to ChecksumAlgorithm types

1.1.0

• Fix various issues where some CRC hashes were totally broken
• All algorithms are now always validated by its check number when initialized for the first time

1.0.9

• Removed obsolete extension methods
• Fixed issues where the CrcConfig hash sizes were wrong in some cases
• Fixed issue where the bit size could be larger than the generic type allows
• Added IChecksumAlgorithm method for text or file encryption
• Added BigInteger type support for CrcConfig
• Added about 50 CRC config presets between 16 and 82 bit

1.0.8

• Fixed issue where array size limit in GetBytes was too large
• Improved CrcConfig struct so that more CRC variations are supported
• Added support for FileInfo objects
• Added Try extensions which suppress exceptions
• Added support for odd bit algorithms
• Removed vulnerable ECB (Electronic Code Book) encryption mode
• Increased the number of supported types of extensions by more than 30 types
• Renamend Encrypt extensions to GetChecksum to avoid name collisions
  • (Obsolete extensions will be removed next version)

1.0.7

• Fixed an issue where the byte order of Adler-32 and CRC-16+32+64 was wrong on big-endian processor architecture
• Removed internal instance caching, which is no longer needed
• Reworked GetGuid extension method so that it combines the bytes of both hashes instead of cutting parts and placing them next to each other
• HMAC encryption is now available for MD5 and SHA-1+2 by setting the SecretKey instance field
  • The SecretKey can be removed from process memory by calling the DestroySecretKey() instance method
• General code improvements, minor fixes and expansion of the documentation

1.0.6

• SymmetricKeyAlgorithm classes are now IDisposable
  • Dispose() will try to completely remove the password and salt from memory. This will only work if there are no other references to these data outside
• Added interface and abstract generic class of ChecksumAlgorithm
• Added CrcConfig structure to quickly create custom CRC classes according to other standards
• Improved caching so that only used types are cached instead of all
• Minor fixes, improvements and code cleanups

1.0.5

• Removed binary-to-text encoding
  • Can be found here: https://github.com/Roydl/Text
• Restruced some classes to avoid name conflicts
• Minor fixes
