📖 How to Use Hash Generator

1
Type or paste your input
Enter any text, password, or data to hash.
2
Choose a hash algorithm
Select MD5, SHA-1, SHA-256, or SHA-512 depending on your security needs.
3
Copy the hash
Click copy to grab the hex-encoded hash for use in your application.

💡 Examples

Password hash (never store plain text!)
INPUT
password123
OUTPUT
SHA-256: ef92b778bafe771e89245b89ecbc08a44a4e166c06659911881f383d4473e94f
MD5 (legacy/checksums only)
INPUT
hello
OUTPUT
MD5: 5d41402abc4b2a76b9719d911017c592

🚀 Pro Tips

Never use MD5 or SHA-1 for passwords — use bcrypt, Argon2, or scrypt instead.
SHA-256 and SHA-512 are suitable for data integrity checks and checksums.
Always add a salt (random string) before hashing passwords to prevent rainbow table attacks.
Hash the same input twice — you should always get the identical output (deterministic).
Use hashes to verify file integrity — compare the hash of a downloaded file with the publisher's hash.

Frequently Asked Questions

Can I reverse a hash to get the original text?+
No — cryptographic hashes are one-way functions. You cannot reverse SHA-256 or MD5. However, weak or common passwords can be found via rainbow tables.
Which hash algorithm should I use?+
For checksums and data integrity: SHA-256 or SHA-512. For passwords: bcrypt, scrypt, or Argon2 (not available here — those are server-side algorithms).
What is the difference between MD5 and SHA-256?+
MD5 produces a 128-bit (32-character hex) hash and is cryptographically broken. SHA-256 produces a 256-bit (64-character hex) hash and is still considered secure for most uses.
