Compute MD5, SHA-1, SHA-256, and SHA-512 hashes for text or files instantly. 100% istemci tarafında — your data never leaves your device. Desteks multiple algorithms, uppercase/lowercase output, and per-line hashing.
A cryptographic hash function is a mathematical algorithm that maps data of arbitrary size to a bit string of a fixed size. Hash values are commonly used to verify data integrity, store passwords securely, and generate unique identifiers. This tool computes MD5, SHA-1, SHA-256, and SHA-512 hashes entirely tarayıcınızda — no data is ever sent to a server.
A hash function takes an input (or "message") and returns a fixed-size string of bytes, typically in hex format. The same input always produces the same output, but it is computationally infeasible to reverse the process.
MD5 is no longer considered cryptographically secure due to known collision vulnerabilities. It is included for compatibility and checksum purposes. For security-critical applications, use SHA-256 or SHA-512.
Evet. Dosyalar are read locally tarayıcınızda using the DosyaReader API. There is no file size limit imposed by this tool — only your browser's memory capacity.
Hexadecimal digits can be represented in uppercase (A-F) or lowercase (a-f). Both represent the same value. The choice is purely cosmetic — select the format that matches your needs.
