File Hash Calculator

Calculate cryptographic hashes (MD5, SHA-1, SHA-256, SHA-512) for file integrity verification.

Click to select file or drag & drop

Any file type supported

Algorithm:

Expected Hash:

No file selected

Upload a file to calculate its cryptographic hashes

File Integrity Verification

Verify downloaded files haven't been corrupted or tampered with

Recommended: SHA-256

Digital Forensics

Create cryptographic fingerprints of evidence files

Recommended: SHA-256 or SHA-512

Software Distribution

Provide checksums for software packages and updates

Recommended: SHA-256

Backup Verification

Ensure backup files are identical to originals

Recommended: MD5 or SHA-256

MD5 (Message Digest 5)

Fast but cryptographically broken. Use only for non-security purposes.

SHA-1 (Secure Hash Algorithm 1)

Deprecated for security use. Vulnerable to collision attacks.

SHA-256

Part of SHA-2 family. Currently secure and widely recommended.

SHA-512

Stronger variant of SHA-2. Provides highest security level.

Collision Resistance

Difficulty of finding two inputs that produce the same hash.

File Integrity

Any change to file content will result in completely different hash.
