1. Block cipher modes for symmetric-key encryption algorithms require plain text input that is a multiple of the block size (ie 128 bits for AES), so messages may have to be padded to bring them to this length.
2. The system uses Cipher Block Chaining method (CBC) to encrypt the message in blocks of 128 bits.
3. The disadvantage of this method is that identical plaintext blocks are encrypted into identical ciphertext blocks; thus, it must not be used with a non-random and repetitive data.
4. This app can be used for encrypting your message text , SMS or email content using Advanced Encryption Standard (AES) with 256 bit key.
5. It allows you to encrypt/decrypt text messages using Advance Encryption Standard(AES) with a 256 bit (key length).
6. In CBC Explicit Initialization Vectors technique is being used wherein we prepend a single random block to the plaintext.
7. The app warns if the user does not selects a password with min 6 characters having atleast one uppercase letter, one lower case, one special character and one digit.
8. Electronic Codebook(ECB) block cipher method option has also been given.
9. Text Encryptor is a Text Encryption application that allows you to protect your privacy while communicating with friends.
10. This block is discarded and the rest of the decryption is the original plaintext.
11. In ECB the message is divided into blocks, and each block is encrypted separately.
1. Please add PIN protection to access password dialogBest app... It decodes other crypted textVery good free app.A very good app does what it saysDoes what it says, best appThere are literally 0 instructions on useage.
2. It doesn't have a lot of options and settings to worry about, just put in the password you want to use and start encrypting and decrypting messages.
3. Please consider adding the ability to utilize the Share feature so we can import text directly into the app.
4. I've come across certain other apps that won't allow me to copy and paste, instead they only offer the ability to share.
5. If you want simple and easy to use, this app is perfect.Awesome! I can use this in conjunction with any messaging app.
6. If you like being able to change settings and use different ciphers, this app might not be for you.
7. "INSTALL" YESCan't decrypt its own cipher text in Legacy Mode.
8. Thank you!If you value privacy this app is worth the download so don't pass it up.
9. It's a very decent app and worth every bit of the 5 stars I'm rating it.
10. Thanks!This app is simple and easy to use.
11. Thus such feature here would help out immensely.
