Sample app for EasyCrypt, a cryptography library for Android.

Secure and efficient cryptography library for Android. (Auto fix SecureRandom bugs in API 18 and below.)

Features:

- AES-256 encryption algorithm

- CBC/CTR mode of operations

- Block padding with PKCS7 (only with CBC)

- Computationally secure random salt (of cipher block size)

- Password stretching with PBKDF2

- Random IV generated on each encryption (16 bytes)

- Supports MD5, SHA1, and SHA2 hash functions

- Generate secure keys with SecureRandom or random.org

- Asymmetric encryption with RSA

- Auto handle large data by using hybrid asymmetric encryption

- Asymmetric RSA signing and verification

- Supported RSA key sizes are 2048 bits and 4096 bits

- Password analysis for strength, crack times, weakness, etc using nulab's zxcvbn4j library
