About These Algorithms
MD5
Produces a 128-bit (32-char) hash. Cryptographically broken — do not use for security.
SHA-1
Produces a 160-bit (40-char) hash. Deprecated for TLS/certificates but still used in checksums.
SHA-256
Produces a 256-bit (64-char) hash. Part of SHA-2, current standard for integrity checks and signatures.
SHA-512
Produces a 512-bit (128-char) hash. Stronger variant of SHA-2 for higher-security checksums.
Bcrypt
A salted, intentionally slow hashing algorithm designed specifically for password storage — the recommended choice of these five.

Frequently Asked Questions
Is this suitable for production password storage?
Production systems should use a dedicated, salted password hashing function built into your framework (like bcrypt or Argon2) rather than a general-purpose online tool.
Is this tool free?
Yes, using this utility is completely free.
Frequently Asked Questions
What does password encryption mean?
In this context, "encryption" refers to cryptographic hashing — converting a password into a fixed-length string using a one-way algorithm. Unlike true encryption, hashes cannot be reversed. This tool computes MD5, SHA-1, SHA-256, SHA-512, and Bcrypt hash outputs for educational and testing purposes.
Are these hashes safe for storing passwords?
MD5, SHA-1, SHA-256, and SHA-512 are all fast general-purpose hash functions — they are NOT safe for password storage on their own because their speed makes brute-force attacks practical. Bcrypt, included here, is purpose-built for passwords: it is intentionally slow and automatically salted, which is why it's the one recommended for real authentication systems (along with scrypt or Argon2).
When would I use MD5 or SHA-1 then?
MD5 and SHA-1 are still commonly used for non-security purposes like file integrity checksums, cache busting, generating unique identifiers, and comparing data without needing the original. SHA-256/SHA-512 are the modern standard for integrity and digital signatures. They're also used when verifying file downloads where the threat model doesn't involve adversarial attacks.
Why is the Bcrypt hash different every time I encrypt the same password?
Bcrypt automatically generates a random salt and embeds it in the output every time you hash a password — that's a deliberate security feature, not a bug. It means two users with the same password get completely different stored hashes, defeating precomputed rainbow-table attacks. MD5, SHA-1, SHA-256 and SHA-512 above are unsalted, so the same input always gives the same output.
Why does the same password always produce the same hash?
Hash functions are deterministic — the same input always produces the same output. This is by design, as it allows you to verify data without storing the original. The downside is that attackers can precompute hashes for common passwords (rainbow tables). Modern password hashing adds a random "salt" to prevent this.
