Is the SHA-3 output here the same as standard SHA3-256 or SHA3-512?

No, and this matters if you are comparing values against another system. The SHA-3 row uses the Keccak algorithm from the crypto-js library with a fixed 512-bit output. Standardised NIST SHA-3, defined in FIPS 202, uses different padding, so the same input gives a different digest. If something downstream expects FIPS 202 SHA3-512, check it against a tool that implements that standard.

Can I hash a file, or only text?

Only text. There is no file input on this page at all, so it cannot compute the checksum of a download. Use the hash tool built into your operating system for files.

Should I use these digests to store passwords?

No. These are single-pass hashes with no salt and no key, and MD5 and SHA-1 are long broken for security purposes. Fast hashes are the wrong tool for passwords in any case — use bcrypt, scrypt or Argon2, which are deliberately slow and salted.

Does it send my input to a server?

No. The hashing library is bundled into the page and runs entirely in your browser. Your text is never transmitted, and it is not saved anywhere.

How to Use

Paste the text you want to hash
This page hashes text only. There is no file upload — to hash a file, use your operating system's own checksum utility.
Read all eight digests at once
MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-3 and RIPEMD-160 are each calculated as you type and shown on its own row, in hexadecimal.
Copy the one you need
Every row has a copy button. The same input always produces the same output here, so you can verify it against another tool.

MD5 Hash: Fast & Lightweight Checksum

MD5 (Message-Digest Algorithm 5) produces a 128-bit hash value, commonly used for file integrity verification and non-critical data checks. Despite known collision vulnerabilities, MD5 remains popular in software downloads, database partitioning, and legacy systems due to its speed and compact output. Use it for quick integrity checks where security is not the primary concern.

SHA-1 Hash: Legacy Security Standard

SHA-1 (Secure Hash Algorithm 1) generates a 160-bit hash, historically used in SSL certificates, Git commits, and digital signatures. Since 2017, it has been considered cryptographically broken and is deprecated for security-sensitive applications. However, it still serves well in non-security contexts like data deduplication or version control systems.

SHA-256: The Industry Standard

SHA-256 is part of the SHA-2 family, producing a 256-bit hash. It is the most widely adopted hash function in modern cryptography, used in blockchain (Bitcoin), TLS certificates, password storage (with salting), and file verification. Its resistance to collision attacks makes it the go-to choice for security-critical applications.

SHA-224: Truncated SHA-256 for Space-Saving

SHA-224 produces a 224-bit hash by truncating SHA-256. It offers the same security level as SHA-256 but with a shorter output, ideal for environments where storage or bandwidth is limited, such as embedded systems or certain cryptographic protocols (e.g., ECDSA).

SHA-512: Maximum Security for Large Systems

SHA-512 delivers a 512-bit hash, offering the highest security margin among SHA-2 variants. It is often used in high-security environments, digital forensics, and when processing very large files. Despite its longer output, it can be faster on 64-bit architectures compared to SHA-256.

SHA-384: Balanced Security & Performance

SHA-384 produces a 384-bit hash by truncating SHA-512. It provides strong security with moderate output length, commonly used in TLS cipher suites, government standards (FIPS), and systems requiring a middle ground between SHA-256 and SHA-512.

SHA-3: The Modern Cryptographic Standard

SHA-3 is the newest member of the Secure Hash Algorithm family, built on a sponge construction rather than the Merkle–Damgård structure used by SHA-2. The standard is defined in FIPS 202, in fixed output lengths (SHA3-224, SHA3-256, SHA3-384, SHA3-512). One caveat about this page: the SHA3 row is computed by the crypto-js library's Keccak implementation at a fixed 512-bit output. Keccak and standardised SHA-3 differ in their padding, so the same input gives a different digest — do not compare this row against a FIPS 202 SHA3-512 value.

RIPEMD-160: Lightweight Alternative

RIPEMD-160 generates a 160-bit hash and is widely used in Bitcoin and cryptocurrency address generation. It offers a different design from SHA-1 and is considered secure for its intended use cases. While not as common as SHA-2, it remains a solid choice for blockchain applications and specialized cryptographic needs.
