0.4.0

• Performance 😲
  • Huge performance improvements.
  • Most of the public methods are now only async: if it can be async, it's async.
  • Adding byte to SafeBytes is now at least 2100% faster
    • Adding single character to SafeString is at least 8200% faster.
  • GetHashCode() in SafeString and SafeBytes is faster than light (0 ms) compared to older implementation (6s for 1000 char with a linear increase per char)
  • Decrypting all bytes in SafeBytes is now 214x faster for 10KB, much faster for bigger sizes (1 MB = 900 ms).
  • AppendAsync(ISafeBytes) and DeepCloneAsync are optimized in SafeBytes
    • It is much faster (from 170 seconds to 37 ms for 10KB data)
    • Leads to much faster ToSafeBytes in SafeString
  • Faster equality checks for bytes and strings without compromising security.
    • SafeBytes.EqualsAsync(bytes) for 100 KB; before: 93032ms, after: 20ms
    • SafeBytes.EqualsAsync(ISafeBytes) for 100 KB before: 183346ms, after: 15ms
    • SafeString.EqualsAsync gains huge performance from inner byte equality, also it does not encrypt & decrypt plain strings anymore.
• Fixed
  • SafeMemoryStream ends up in infinite loop while reading when its empty.
  • Cannot change AlertChannel on SafeContainer
• Added
  • Encryption
    • Support for padding in Blowfish algorithm.
    • Both fast & safe (AES + Blowfish) supports setting padding mode.
  • AppendMany() to append multiple bytes to SafeBytes
  • Added constructor that writes the given binary to SafeMemoryStream
  • Added RevealDecryptedBytesAsync in SafeString
  • Added immutable interfaces IReadOnlySafeString and IReadOnlySafeBytes
  • Injection message includes the type of the injected objects.
• Changed
  • ❗ Replaced sync methods with async variants.
  • Simplified builds: targets only netstandard2.0, netstandard1.6 and NET4.5.
  • Namespace changes for better modular structure
  • Refactorings & better documentation.
  • Renamed decrypting methods in SafeBytes, SafeByte and SafeString with RevealDecrypted prefix.
  • Simplified revealing SafeString, now its through RevealDecryptedStringAsync on SafeString.
• Removed
  • SafeString.ToSafeBytesAsync is removed because of its inefficiency.

0.3.1

Changed

• Using .ConfigureAwait(false) in async methods to better support UI applications.
• More strict disposed checks
• SafeString & SafeBytes can be revealed truly thread-safe.

Fixed

• Issue with SafeBytes causing some logic to fail is solved (wrong arbitrary byte logic after 0.3.0).
• ToByteArray in SafeBytes leads to corrupted memory.
• SafeMemoryStream: Fixed stackoverflow in .NET Framework and .NET Standard 2.0
• SafeString / Bytes cannot be revealed twice: bug with encryption of inner bytes
