Text Hash Generator

📖 Tool Introduction

The text hash generator computes several digests for one piece of text at once, for checking, comparing and troubleshooting. It covers five common algorithms: MD5, SHA-1, SHA-256, SHA-384 and SHA-512. Tick whichever you need and only those are produced, so you get every result in one pass instead of switching tools or pasting the same text repeatedly.

The situations are specific. After downloading a file you want to check the published checksum, so paste the content and compare. When an API signature does not match the documented example, comparing digests is the fastest way to see whether the string you assembled is identical. When a suspicious fragment appears in a log and you want to know whether it equals another fragment without reading both word by word, a digest answers immediately. When deduplicating data, turning long text into fixed length digests makes comparison far cheaper.

The five algorithms serve different purposes. MD5 and SHA-1 are old and the most broadly compatible, still used by plenty of legacy systems and interfaces, but neither is appropriate for security any more; they are offered here for checksums and interop, not for protection. SHA-256 is the common default today, balancing speed and strength. SHA-384 and SHA-512 produce longer output and suit cases more sensitive to collisions.

Output supports case switching. Most systems publish lowercase hexadecimal, but some documentation and older tooling uses uppercase, so a quick switch lets you compare directly without converting by hand. Results appear one algorithm per line with the names aligned at a fixed width, and long digests wrap automatically so they never overflow on a narrow screen.

All computation happens locally in the browser: MD5 comes from a built-in implementation and the SHA family goes through the browser Web Crypto interface, so the text never leaves your device. What you paste is often signature source strings, config files or content carrying tokens, which makes local computation less of a nicety and more of a prerequisite for using the tool at all.

✨ Key Features

• Five algorithms in one pass: MD5, SHA-1, SHA-256, SHA-384 and SHA-512 in any combination
• Case switching: flip between lowercase and uppercase hexadecimal to match how different systems write it
• Local computation: MD5 from a built-in implementation, SHA via browser Web Crypto, nothing uploaded
• Aligned line output: names at a fixed width and digests that wrap, so nothing overflows on narrow screens
• Results you can take away: copy every digest at once or export them to a text file
• Correct for multibyte text: always hashed as UTF-8, so Chinese text and emoji come out right

🚀 How to Use

1. Paste the text you want hashed into the input box on the left
2. Tick the algorithms you need in the right column; MD5 and SHA-256 are on by default
3. Switch letter case to upper if you need uppercase output
4. Press start; the result area lists the digest for each algorithm line by line
5. Press copy to take everything, or download to save it as a text file

⚠️ Things to Note

• A digest is not encryption: Hashing is one way and does not protect content; anyone with the original computes the same value
• MD5 and SHA-1 are no longer safe: Use them only for checksums and legacy interop, never for passwords or signatures
• Use dedicated algorithms for passwords: Password storage belongs to slow algorithms such as bcrypt, Argon2 or scrypt
• Results depend on encoding: Hashing is done as UTF-8; a different encoding on the other side yields a different digest
• Whitespace counts too: Trailing spaces and newlines are part of the input, so both sides must match exactly before comparing
