Encrypt Decrypt is an app for the security conscious to encrypt/decrypt plain text using Advanced Encryption Standard (AES) 256-bit encryption with a symmetric plain text key.
The cryptographic key is derived with PBKDF2 using a 64-bit random Salt along with the specified plain text key. A total of 25,600 iterations are used while generating the cryptographic key to improve cryptographic strength and protect against brute force attack. Salt helps to prevent vulnerability to dictionary attack.
The encrypted text is encoded to Base64 so as to allow easy saving, sharing and transmission.
The app allows you to share the encrypted text and also accepts any shared text for encryption/decryption.
Download from Google Play Store. Please rate and review the app!
For using on a standalone PC also see Encrypt Decrypt for Java, which also support encryption/decryption of files.
