Mô tả
Text Encryptor is a Text Encryption application that allows you to protect your privacy while communicating with friends. It allows you to encrypt/decrypt text messages using Advance Encryption Standard(AES) with a 256 bit (key length).
The system computes the 256 bit key from the password string using SHA-256. The system uses Cipher Block Chaining method (CBC) to encrypt the message in blocks of 128 bits. 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. The padding being used is PKCS5Padding. In CBC Explicit Initialization Vectors technique is being used wherein we prepend a single random block to the plaintext. Encryption is done as normal, except the IV does not need to be communicated to the decryption routine. Whatever IV decryption uses, only the random block is "corrupted". This block is discarded and the rest of the decryption is the original plaintext.
Electronic Codebook(ECB) block cipher method option has also been given. In ECB the message is divided into blocks, and each block is encrypted separately.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. The ECB mode is deterministic. ECB option is only for academic purpose.
Test Mode. AES test values (taken from FIPS-197) are:
Key: 000102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1f
Plaintext: 00112233445566778899aabbccddeeff
Ciphertext: 8ea2b7ca516745bfeafc49904b496089
Encrypting the plaintext with the key should give the ciphertext, decrypting the ciphertext with the key should give the plaintext.
You can test the encryption online by using the test values at
http://extranet.cryptomathic.com/aescalc/index
To test select the mode as ECB on the website and use the above test values. To test for anyother value of Key and data , ensure that the data is exactly 16 Hex (16x8=128 bits) characters long. The key should be 32 Hex characters (32x8=256 bits) long. The mode selected in the android application should be "Testing with No Padding". You would observe that the result matches exactly.
