When you need to quickly process sensitive data but lack professional encryption software, this tool provides instant encryption and decryption capabilities based on the DES algorithm. DES (Data Encryption Standard) is a symmetric-key algorithm that uses a 56-bit effective key to encrypt or decrypt 64-bit data blocks. The tool directly outputs ciphertext in Base64/Hex format or the decrypted original text.
Encryption and decryption must use the exact same key and mode. The IV for CBC mode must be kept intact. Text is encoded in UTF-8 by default. Please do not use this tool to process highly sensitive data.
For testing, you can use the example key "01234567" to encrypt the text "Hello" in CBC mode (with the IV set to "00000000") and observe the changes in the Base64 output. In real-world applications, always use a cryptographically secure random key generator.
