MD5 Hash Generator

Generate MD5, SHA-1 and SHA-256 hashes from any text string instantly in your browser.

Enter text to hash

Uppercase output

MD5 (128-bit)

SHA-256 (256-bit)

SHA-512 (512-bit)

ℹ️ All hashing is done locally in your browser. No text is sent to any server. MD5 is not suitable for security-critical password hashing — use it for checksums and non-security purposes.

What is this tool?

An MD5 hash generator is a free developer tool that generates cryptographic hash values from any text input. It supports MD5, SHA-1, SHA-256 and SHA-512 algorithms. Hash functions are one-way — they convert input data to a fixed-length fingerprint that cannot be reversed.

How to Use

Enter your text or dataType or paste the string, password or data you want to hash.

Select the hash algorithmChoose from MD5 (32 chars), SHA-1 (40 chars), SHA-256 (64 chars) or SHA-512 (128 chars).

Copy the hash valueClick Copy to grab the hash string and use it in your code, database or security verification.

Common Uses

🔒

Password Hashing

Store hashed passwords in databases instead of plain text. Note: use bcrypt or Argon2 for passwords, not MD5.

✅

File Integrity

Generate a hash of a file to verify it has not been corrupted or tampered with during download or transfer.

🔑

API Authentication

Create HMAC signatures for API request authentication using hash functions.

🔍

Data Deduplication

Hash records to quickly identify duplicate entries in large datasets without comparing full content.

Frequently Asked Questions

What is MD5?

MD5 (Message Digest 5) produces a 128-bit (32 character hex) hash value. It was once used for password hashing but is now considered cryptographically broken and should not be used for security-critical purposes.

Is MD5 safe for passwords?

No. MD5 is fast to compute, which makes it vulnerable to brute-force and rainbow table attacks. Use bcrypt, Argon2 or PBKDF2 for password hashing in production applications.

What is the difference between MD5 and SHA-256?

SHA-256 produces a 256-bit (64 character) hash and is significantly more secure than MD5. SHA-256 is part of the SHA-2 family and is widely used in TLS, Bitcoin and digital signatures.

Can a hash be reversed?

No — hash functions are one-way. The same input always produces the same hash, but you cannot compute the original input from the hash. However, common inputs can be matched via precomputed rainbow tables.
