什么是Hash Generator？
A Hash Generator creates cryptographic hashes (MD5, SHA-1, SHA-256, etc.) from text or files. Useful for verification and security.
如何使用
输入 text or upload a file and select the hash algorithm. The hash value is generated instantly.
常见问题
What is a hash generator?
A hash generator is a tool that converts an input of any length (like text or a file) into a fixed-size string of characters, known as a hash or digest. This is typically used to verify data integrity.
Which algorithms are supported?
This calculator supports popular hashing algorithms including MD5, SHA-1, SHA-256, SHA-384, and SHA-512. These algorithms generate different output lengths and offer varying levels of security.
Is hashing the same as encryption?
No, hashing is not encryption. Encryption is a two-way function that can be decrypted to retrieve the original data. Hashing is a one-way function; you cannot convert a hash back to the original input.
Why do different inputs sometimes look the same?
They actually should not. A hash function is designed to produce a unique output for every unique input. However, extremely rare events called 'collisions' can happen where two different inputs produce the same hash, though this is unlikely with secure algorithms like SHA-256.
Can I use this to securely store passwords?
While you can generate a hash for a password, standard hash algorithms (like SHA-256) are too fast for secure password storage. You should use specialized algorithms like bcrypt, Argon2, or PBKDF2 which include 'salting' to protect against brute-force attacks.
Does changing the text case affect the hash?
Yes, hashing is case-sensitive. The hash for 'Hello' will be completely different from the hash for 'hello'.
What is the difference between SHA-1 and SHA-256?
SHA-1 produces a 160-bit hash and is considered cryptographically weak due to vulnerabilities. SHA-256 produces a 256-bit hash and is part of the SHA-2 family, making it much more secure and widely recommended today.
