About This Tool
What is Hash Generator?
A tool for generating hash values from text. Supports major hash algorithms including MD5, SHA-1, SHA-256, and SHA-512. Used for file integrity verification, password hashing, and data checksum validation.
How to Use
- Select a hash algorithm (MD5, SHA-1, SHA-256, SHA-512).
- Enter the text to hash in the input area.
- The hash value is automatically generated.
- Copy the result for your use.
Key Features
- Supports MD5, SHA-1, SHA-256, SHA-512 algorithms
- Automatic hash calculation on input
- One-click result copying
- Uses browser's built-in Web Crypto API
Tips
- SHA-256 is the most widely used secure hash algorithm today.
- MD5 and SHA-1 are not recommended for security purposes but still useful for checksums.
- The same input always produces the same hash value, making it ideal for data integrity verification.

Frequently Asked Questions
Por que MD5 e SHA-1 são inseguros?▼
Vulnerabilidades de colisão conhecidas. Colisões MD5 em segundos. Use SHA-256+ para segurança.
Posso reverter um hash?▼
Não — função unidirecional. Senhas comuns encontráveis via rainbow tables, por isso use salt.
Hashing vs criptografia?▼
Hashing: unidirecional, digest fixo. Criptografia: bidirecional com chave. Hashing para integridade; criptografia para recuperação.
