Category: Properties: Value: Comments: Basic: Property: data Type: String Default: ' Barcode value to encode Data Matrix Valid Data Char Set: ASCII values 0 - 127 in accordance with the US national version of ISO/IEC 646 NOTE: This version consists of the G0 set of ISO/IEC 646 and the C0 set of ISO/IEC 6429 with values 28 - 31 modified to FS, GS, RS and US respectively. The Base64 encoding process takes 24-bit strings (3 letters) and breaks them into four 6-bit chunks, mapping the resulting binary number to the Base64 alphabet. So, lets take a look at our previous example, the string 'yessir'. 8-bit binary: 011011 011100.
Learn to use Java AES 256 bit encryption to create secure passwords, and decryption for password validation. To read simple AES encryption, read linked post.
1. AES – Advanced Encryption Standard
AES is a symmetric encryption algorithm. It was intended to be easy to implement in hardware and software, as well as in restricted environments and offer good defenses against various attack techniques.
AES is block cipher capable of handling 128 bit blocks, using keys sized at 128, 192, and 256 bits. Each cipher encrypts and decrypts data in blocks of 128 bits using cryptographic keys of 128-, 192- and 256-bits, respectively. It uses the same key for encrypting and decrypting, so the sender and the receiver must both know — and use — the same secret key.
In below encryption and decryption example, I have used base64 encoding in UTF-8 charset. It is done for displaying the output of program. If your application, you can store and validate the data in byte array format as well.
2. AES 256 Encryption
Java program to encrypt a password (or any information) using AES 256 bits.
Do not forget to use same secret key and salt in encryption and decryption.
3. AES 256 Decryption
Java program to decrypt a password (or any information) using AES 256 bits.
4. Java AES 256 Example
Let’s test our AES256 encryption and decryption methods with a simple string.
Program output.
Clearly, we are able to use AES256 encryption to encrypt a string, and decryption to get back original string from encrypted string.
Happy Learning !!
