DES decryption tool description

Tool Description

This tool provides standard DES(Data Encryption Standard) The tool provides standard DES algorithm online implementation, support:- ** 64-bit key encryption/decryption **- ** ECB electronic codebook mode **- ** real-time bi-directional encryption/decryption conversion **.

Core Functions

Encryption Function: Input plaintext and key, automatically generate DES encryption results

Decryption function: Input the ciphertext and encryption key to restore the original content.

Key Requirement: Support 8-byte (64-bit) ASCII character key, recommended to include a combination of letters, numbers and symbols.

Usage Scenario

- Network security teaching demonstration - data transmission protection test - encryption algorithm research - system development debugging

Cautions

1. DES algorithm is considered to be of low security strength, and is recommended to be used only in the test environment. 2. Please keep the encryption key in a safe place, as it will not be able to decrypt the data if it is lost. 3. It is recommended to use more secure algorithms, such as AES, for large files.

Technical Parameters

- Compliant with FIPS PUB 46-3 standard - 56-bit effective key length - 64-bit packet size - 16-round Feistel structure
