Hash Generator | MD5, SHA-1, SHA-256, SHA-512
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from text for checksums, integrity checks, and developer testing.
Generate Text Hashes
Type or paste text to calculate MD5, SHA-1, SHA-256, and SHA-512 digests. Hashes are useful for comparing content, checking integrity, and creating repeatable test values.
Hashing Is Not Encryption
A hash cannot be decrypted back into the original text. MD5 and SHA-1 are not suitable for modern security decisions, but they are still seen in legacy checksums and quick comparisons.
When to Use SHA-256 or SHA-512
Use stronger SHA-2 hashes for integrity checks and development workflows where collision resistance matters. For password storage, use password hashing algorithms such as bcrypt, Argon2, or PBKDF2 instead.
About This Tool
Hash Generator computes cryptographic hash values for any text input using algorithms including MD5, SHA-1, SHA-256, and SHA-512. Hashes are used to verify data integrity, store passwords, generate checksums, and compare files without exposing their content.
When to Use It
Use this to generate a SHA-256 hash of a file checksum for verification, to produce a test hash during development, or to compare whether two pieces of text are identical without reading either one.
How to Use
- Paste or type your text into the input field.
- Select the hashing algorithm from the dropdown.
- Click Hash to generate the output.
- Copy the hash value for use in your application or verification.
Frequently Asked Questions
Is MD5 still safe to use?
MD5 is considered cryptographically broken and should not be used for security-sensitive purposes such as password hashing. It is still useful for non-security checksums.
Can I reverse a hash back to the original text?
No. Hashing is a one-way function. A hash cannot be reversed to its input by design. Matching input produces the same hash, which is how verification works.
What is the difference between SHA-256 and SHA-512?
SHA-512 produces a longer hash (512 bits vs 256 bits) and is slightly more computationally intensive. Both are considered secure for current use.
