Algorithm Reference

Algorithm	Output Length	Notes
MD5	128-bit (32 hex)	Fast but cryptographically broken, use for checksums only
SHA-1	160-bit (40 hex)	Deprecated for security, still used for git commits
SHA-256	256-bit (64 hex)	Recommended for most security applications
SHA-384	384-bit (96 hex)	Truncated SHA-512, good balance of security/speed
SHA-512	512-bit (128 hex)	Maximum security, slightly slower

In Laravel

Do not store passwords with any hash on this page. MD5 and the SHA family are fast, and speed helps an attacker who tries billions of guesses. Laravel's Hash facade uses bcrypt by default, with Argon2 as an option. Both are slow on purpose and add a random salt.

use Illuminate\Support\Facades\Hash;

$user->password = Hash::make($request->password);

if (Hash::check($request->password, $user->password)) {
    // The password is correct
}

The fast hashes are right for checksums and signatures. SHA-256 of a file finds duplicate uploads, and an HMAC proves that a webhook came from the sender that knows the secret:

$checksum = hash_file('sha256', $request->file('invoice')->path());

$expected = hash_hmac('sha256', $request->getContent(), config('services.shop.webhook_secret'));

// hash_equals() compares in constant time, so timing does not leak the signature
abort_unless(hash_equals($expected, (string) $request->header('X-Signature')), 403);

Multiple Algorithms

Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes simultaneously from a single input.

100%

Client-Side

All hashing happens in your browser. Your data never leaves your computer.

File Hashing

Hash files of any type. Drag and drop or browse to verify file integrity with checksums.

Frequently Asked Questions

Does Laravel's hashName() hash the file contents?

No. $request->file('photo')->hashName() returns 40 random characters plus the file extension. It does not read the file, so two uploads of the same file get different names. To find duplicates, store hash_file('sha256', $path) next to the file and compare that.

Is MD5 still safe to use?

Not for anything an attacker can influence. Researchers produced MD5 collisions in 2004, and the first public SHA-1 collision followed in 2017. MD5 still detects accidental corruption, for example in a cache key or a download check you control. For signatures, tokens and anything else security-related, use SHA-256 or stronger.

Why does my terminal give a different hash for the same text?

The input is not the same. echo "hello" | sha256sum hashes "hello" plus a newline character. Use printf '%s' 'hello' | sha256sum to hash only the text. Spaces at the end of a line and Windows line endings change the hash too.
