About These Algorithms

DES (crypt)

Legacy Unix password hashing. Uses 56-bit key. Obsolete for security — for reference only.

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.

About Password Encryption Utility

The Password Encryption Utility is a free online tool that encrypts any text string using multiple cryptographic hash algorithms — including MD5, SHA-1, SHA-256, SHA-512 and more. Hashing converts your input into a fixed-length, one-way encrypted string that cannot be reversed to the original text (unlike two-way encryption).

Hashing is used in web development and database management to store passwords securely. Instead of storing a plain-text password, applications store its hash — when a user logs in, the entered password is hashed and compared against the stored hash.

Available Algorithms

MD5 — 32-character hash (fast, not recommended for passwords)
SHA-1 — 40-character hash (legacy, avoid for new systems)
SHA-256 — 64-character hash (current standard for many applications)
SHA-512 — 128-character hash (high security)

Security Advice

For storing user passwords, use bcrypt, scrypt or Argon2 — not MD5 or SHA-1. These older algorithms are too fast and vulnerable to GPU brute-force attacks. This tool is for development, testing and educational purposes. Free, no login required.

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 demonstrates DES, MD5, and SHA-1 hash outputs for educational and testing purposes.

Are these hashes safe for storing passwords?

No — DES, MD5, and SHA-1 are all considered insecure for password storage. They are too fast, making brute-force attacks practical. Modern applications use dedicated password-hashing algorithms like bcrypt, scrypt, or Argon2, which are designed to be slow and include automatic salting.

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. They're also used when verifying file downloads where the threat model doesn't involve adversarial attacks.

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.
