SHA3 (Message Digest Algorithm 5) is a widely used cryptographic hash function that produces a 128-bit (16-byte) hash value, used to ensure information transmission integrity.
Characteristics
One-way encryption: SHA3 is a one-way hash function, cannot reverse hash value to original data
Fixed length: Regardless of input length, SHA3 output is always a 32-character hexadecimal string
Fast calculation: SHA3 algorithm is fast, suitable for large amounts of data processing
Data integrity verification: Commonly used to verify if files or data have been tampered with
Use Cases
Password storage (not recommended, suggest using more secure algorithms like bcrypt)
File integrity verification
Data fingerprint generation
Digital signatures
Example
Input:Hello World
Output:e167f68d6563d75bb25d3f4937a1f451
