v2.0.1 - All C++ port

Library is ported to C++. Java code is a wrapper around it.

v1.1.3 - Smaller native libraries

Compiler configuration was changed to include only used code from OpenSSL library. Especially important if containing application is not splitted by architecture, therefore containing binaries for all archs at once.

WARNING: This release is from Sep'16.
Look for latest version!

v1.1.2 - 256-bit encryption

• AndroidConceal factory class (and Conceal base class for other configurations)
• 256-bits encryption available
• Entity.create(...) for platform-independent entities: see #138

See README.md for new ways of creating a Crypto and Entity and how old code still works.

v1.0.7 - OpenSSL 1.0.2g + works in Android M

This is v1.0.6 fixed for Android M

• native code is compiled with Position Independent Code (PIC) flag
• an extra instrumentation test is added that test the fix when run on an Android 6 emulator (x86)

v1.0.6 - OpenSSL 1.0.2g

IMPORTANT: don't use this version. Use 1.0.7 instead which includes a fix in native code compilation.

• Integrates OpenSSL 1.0.2g
  • 1.0.2e was tagged as buggy by Google
  • not updated apps will not be able to be in Google Play from July
• Fixes a 4 bytes memory access in native when copying the IV (on encryption and decryption)

v1.0.5 - PBKDF2, InputStream.skip

New features:

• PBKDF2 (class PasswordBasedKeyDerivation)
• Decrypting InputStream implements skip

Fixes:

• Decrypting InputStream: Initial IV read could been truncated if underlying input stream didn't have enough available bytes
• Documentation: troubleshooting section added with proguard typical issue

v1.0.4 - 64bit archs, openssl 1.0.2e, perf improvements

This release includes:

• upgrade to openssl 1.0.2e encryption
• support for 64 bits platforms
• minor code and documentation fixes
• Performance improvement for streams:
  • reading uses the same client buffer, no need for extra allocation
  • no artificially chunked decryption reduces JNI calls (N div 256 for a reading buffer of size N)
  • writing can receive an auxiliar buffer allocated by the client reducing JNI calls by the same proportion and enabling buffer reuse
