Hash Generator
The hash generator creates SHA-256 and MD5 digests from text. Hashes are useful for checksums, examples, cache keys, content fingerprints, and debugging integrations that compare digest values.
SHA-256 is the stronger modern option for integrity checks. MD5 is included because legacy systems still expose it, but it should not be used for password storage or security-sensitive signatures.
Hash generator
Generate SHA-256 and MD5 hashes from text.
What this tool does
A hash function turns input into a fixed-length digest. Developers use hashes for checksums, content fingerprints, cache keys, integrity checks, and compatibility with APIs that ask for digest values.
This tool generates SHA-256 and MD5 hashes from pasted text. SHA-256 is appropriate for modern integrity uses. MD5 is included for legacy debugging, but it is not safe for security-sensitive uses such as password storage or signatures.
Common use cases
Create API examples
Generate digest values for documentation and test fixtures.
Debug legacy integrations
Check MD5 values when maintaining older systems that still expose them.
Example before and after
A small input change creates a very different digest, which makes hashes useful for integrity checks.

- Paste the text you want to hash.
- Click Generate Hashes.
- Copy the SHA-256 or MD5 output.
Common errors
Using MD5 for security
MD5 has known collision weaknesses and should not protect sensitive systems.
Hashing different encodings
Whitespace, line endings, and Unicode normalization can change digest output.
Expecting hashes to decrypt
Hashes are one-way. They are not encrypted text that can be decoded.
Why use this tool
Create test digests for API examples.
Compare text fingerprints quickly.
Debug legacy MD5 or modern SHA-256 values.
Best practices
Prefer SHA-256
Use SHA-256 for modern integrity and fingerprinting tasks.
Normalize input
Make sure both systems hash the exact same bytes.
Do not hash passwords directly
Use dedicated password hashing algorithms such as Argon2, bcrypt, or scrypt.

SHA256 vs MD5
SHA-256 is a modern cryptographic hash. MD5 remains common in legacy checks but is broken for security uses.
What is a UUID
UUIDs are standardized identifiers that can be generated independently with a very low chance of collision.
Best practices for working with API responses
API responses are easier to debug when you validate syntax, format payloads, inspect errors, and compare changes deliberately.
FAQ
Is MD5 secure?
No. MD5 is broken for security use. It is included for legacy compatibility checks only.
Can a hash be reversed?
A cryptographic hash is one-way, but weak inputs can be guessed with dictionaries.
Does this hash files?
No. This tool hashes pasted text only.
Is the text uploaded?
The tool runs in your browser and does not require login, a database, or server-side processing.
