- Producing file fingerprints to detect unauthorized modifications
समस्या निवारण
Hash output differs from expected value
समाधान
Hash functions are case-sensitive and whitespace-sensitive. Ensure there are no trailing spaces or newlines in your input. Even a single extra space produces a completely different hash.
MD5 or SHA-1 is not available
समाधान
MD5 and SHA-1 are considered cryptographically broken and are intentionally not offered. Use SHA-256 or higher for all security-critical applications.
Hash of the same input keeps changing
समाधान
Hash functions are deterministic — the same input always produces the same output. If hashes differ, there is a difference in input (e.g., encoding, whitespace, or newlines). Check for hidden characters.
अक्सर पूछे जाने वाले प्रश्न
Is MD5 supported?
MD5 is not supported because it is considered cryptographically broken — collision attacks have been demonstrated. Use SHA-256 or higher for all security applications. SHA-256 is widely supported and provides strong integrity guarantees.
What is a cryptographic hash?
A cryptographic hash is a fixed-length string produced by a one-way mathematical function applied to any input. The same input always produces the same hash, but different inputs (even differing by one character) produce completely different hashes.
Can I use SHA-256 to store passwords?
Not directly. Raw SHA-256 is too fast, making brute-force attacks feasible. Use a password-specific algorithm like bcrypt, Argon2, or PBKDF2 which are intentionally slow and include salting. SHA-256 is appropriate for data integrity verification.
What is the difference between SHA-256 and SHA-512?
Both are part of the SHA-2 family. SHA-256 produces a 256-bit (64 hex character) digest; SHA-512 produces a 512-bit (128 hex character) digest. SHA-512 is slightly more secure but produces a longer output. SHA-256 is the most widely used.
Can two different inputs produce the same hash (collision)?
Theoretically yes, but for SHA-256 and SHA-512 no practical collision has ever been found. Collisions are computationally infeasible with current technology, making these algorithms secure for integrity verification.
Why does hashing the same text always give the same result?
Hash functions are deterministic algorithms — they always map the same input to the same output. This property is essential for use cases like integrity checks, where you compare a known-good hash against a freshly computed one.
Is my data sent to a server?
No. Hashing is performed in your browser using the Web Crypto API (window.crypto.subtle). Your input text never leaves your device and is not transmitted or stored anywhere.
Can I hash a file instead of text?
The text input mode hashes text strings. If you need to hash a file, read the file content as text or ArrayBuffer and hash it — file hashing may be added as a feature in a future update.
