MD5 is an algorithm that produces a 128-bit sequence (32 hexadecimal characters) from any text. It was widely used for checksums and integrity verification, but it should not be used for passwords, as it is considered cryptographically broken.

SHA-256 is part of the SHA-2 family, generates 256-bit hashes (64 hexadecimal characters) and is widely used for file integrity, digital signatures and blockchain. It is considered safe for these use cases, but for passwords prefer salted algorithms such as Bcrypt.

When should I use Bcrypt?

Bcrypt is the recommended algorithm for storing passwords. It applies a random salt and has an adjustable cost factor (rounds) that makes brute-force attacks impractical. For most systems, 10 to 12 rounds is the ideal balance between security and performance.

Can I use MD5 or SHA-256 to store passwords?

No. Both are too fast and allow dictionary attacks and rainbow tables. For passwords, use slow, salted algorithms such as Bcrypt, Argon2 or scrypt.

Is the text I type here sent to any server?

No. All calculations happen locally in your browser. No text and no hash are sent to ToolboxHub servers.

Why do two bcrypts of the same text come out different?

Bcrypt uses a random salt every time, so the same text produces different hashes. Verification does not compare hashes directly: it applies the salt embedded in the original hash to the new text and compares the result.

About the Hash Generator

Generate MD5, SHA-256 and Bcrypt hashes from any text, entirely in your browser. Useful for verifying file integrity, comparing checksums, generating tokens and creating password hashes during development. No text is sent to any server — every calculation happens locally.

How to generate a hash in 4 steps

Choose the algorithm (MD5, SHA-256 or Bcrypt).
Paste or type the text to convert.
For Bcrypt only: adjust the cost (rounds). Default: 10.
Click Generate and use the Copy button.

Difference between MD5, SHA-256 and Bcrypt

Algorithm	Size	Ideal use	Safe for passwords?
MD5	128 bits / 32 chars	Checksum, integrity	No
SHA-256	256 bits / 64 chars	Signatures, blockchain, integrity	Not recommended
Bcrypt	~60 chars (with salt)	Password storage	Yes
