Description
Encoding Tool
A powerful encoding/decoding tool that supports multiple encoding formats, hash algorithms, and utility tools. Automatically detects system language and supports multi-language switching.
Main Features
① URL Encoding/Decoding
Supports URL encoding operations, converting special characters to URL-standard encoded formats to ensure URL validity and security, avoiding request issues caused by special characters. Can decode encoded URLs, restoring encoded characters to their original form for easy viewing and modification of original URL information.
② Base64 Encoding/Decoding
Provides Base64 encoding functionality, converting binary data, text, etc. to Base64 format, commonly used for transmitting longer identifiers, encrypted data, etc. in HTTP environments to ensure data transmission integrity. Allows users to decode Base64-encoded data, restoring it to original data or text.
③ HTML Entity Encoding/Decoding
Supports HTML entity encoding and decoding, converting HTML special characters to entity codes (e.g., < → <), and can restore entity codes to original characters. Very useful for processing HTML content, preventing XSS attacks, and other scenarios.
④ Hash Algorithm Encoding
Supports multiple hash algorithms including MD5, SHA1, SHA224, SHA256, SHA384, SHA512. These are one-way hash functions used for data integrity verification, password storage, etc. Note: Hash algorithms do not support decoding operations.
Supported Algorithms:
- MD5: 128-bit hash value
- SHA1: 160-bit hash value
- SHA224: 224-bit hash value (SHA2 series)
- SHA256: 256-bit hash value (SHA2 series)
- SHA384: 384-bit hash value (SHA2 series)
- SHA512: 512-bit hash value (SHA2 series)
⑤ Unicode Encoding/Decoding
Supports Unicode encoding and decoding, converting text to Unicode escape sequences (e.g., \u0048\u0065\u006c\u006c\u006f), and can restore Unicode escape sequences to original text.
⑥ Hexadecimal Encoding/Decoding
Supports hexadecimal encoding and decoding, converting text to hexadecimal strings (e.g., Hello → 48656c6c6f), and can restore hexadecimal strings to original text.
⑦ UUID/GUID Generation
Can generate identifiers that comply with the Universal Unique Identifier (UUID) standard. UUIDs are widely used unique identifiers in software construction for uniquely identifying objects or entities. Supports batch generation (1-100), simply enter the count in the input box.
