Common Uses
Example Inputs
Examples of Real-World Usage
6 real-world examples
Password Storage
Hash passwords before storing in databases. Never store plain text passwords - use SHA-256 or SHA-512 with salt for secure password storage.
File Integrity Verification
Verify downloaded files haven't been corrupted or tampered with by comparing SHA hashes. Essential for software downloads and updates.
Version Control & Git
Git uses SHA-1 hashes to track commits and file changes. Understand how version control systems ensure data integrity.
Data Deduplication
Identify duplicate files or content by comparing SHA hashes. Widely used in backup systems and cloud storage.
Digital Signatures
Create message digests for digital signatures. Hash the document, then sign the hash with your private key.
Blockchain & Cryptocurrency
SHA-256 is the foundation of Bitcoin mining and blockchain verification. Essential for understanding cryptocurrency technology.

Frequently Asked Questions
Everything you need to know about our process, pricing, and technical capabilities.
See Full FAQSHA (Secure Hash Algorithm) is a cryptographic hash function that converts input data into a fixed-size string of characters. It's one-way (cannot be reversed) and deterministic (same input always produces the same hash).
SHA-256 produces a 256-bit (64 character) hash while SHA-512 produces a 512-bit (128 character) hash. SHA-512 is more secure but slower. SHA-256 is the industry standard for most applications.
No, SHA-1 is deprecated and should not be used for security purposes. Collisions have been demonstrated. Use SHA-256 or higher for any security-sensitive applications.
SHA-3 is the latest member of the SHA family, designed as an alternative to SHA-2. It uses a different internal structure (Keccak) and is considered equally secure to SHA-2 but with different performance characteristics.
No, SHA hashing is one-way and cannot be reversed. This is by design - it makes SHA hashes perfect for password storage and data integrity verification.
Generate a hash of the original file, then compare it with the hash of the downloaded file. If they match exactly, the file is intact and unmodified.
Both are valid - hashes are case-insensitive when comparing. Lowercase is more common in web development, while uppercase is often used in security documentation.
Theoretically yes (called a collision), but it's astronomically unlikely with SHA-256 or higher. This is why these algorithms are considered cryptographically secure.
