Online AES encryption and decryption tool, can set AES encryption and decryption key, encryption mode, padding method, offset and other parameters, the encryption strength is higher than DES, 3DES.
Online AES encryption and decryption tool, can set AES encryption and decryption key, encryption mode, padding method, offset and other parameters, the encryption strength is higher than DES, 3DES.
The AES encryption and decryption method is one of the most popular and secure symmetric encryption algorithms at present, and can replace the slightly less secure DES and 3DES encryption algorithms. AES encryption adopts a symmetric block cipher system. The length of the key is at least 128, 192, and 256 bits, and the encrypted block length is 128 bits. If the length of the data block and the key is insufficient, it will be supplemented for encryption.
This AES encryption and decryption tool is an advanced version. The encryption mode can be set to CBC, ECB, CTR, OFB, and CFB. The padding mode supports pkcs7padding, pkcs5padding, zeropadding, no padding and other methods. In addition to CBC mode, you need to set encryption and decryption. offset.
By default, the tool uses utf8 to encode and decode the encrypted content, key, and offset. Attention should be paid to the actual encryption and decryption verification; pkcs5padding uses the pkcs7padding padding method to encrypt and decrypt.
