Hash Generator
Create SHA-1 or SHA-2 digests from exact UTF-8 text and compare hexadecimal output.
The browser textarea value is encoded as UTF-8. Spaces, case, and Unicode normalization are preserved. Browser textarea line breaks are represented as LF.
Generated Digest
Browser-local processing
Digest generation runs in this browser with Web Crypto. Yoryantra does not need to upload the text to calculate the result. A browser extension, clipboard action, screen recording, or compromised device can still expose sensitive input, so production secrets are better handled in an approved local workflow.
The digest is a fingerprint of bytes, not appearance
SHA functions operate on bytes. Here, the text is first encoded as UTF-8, then the selected SHA algorithm produces a fixed-size digest. Two inputs that look the same on screen can still differ at the byte level because of spaces, line endings, case, or Unicode normalization.
That distinction matters when reproducing an API example or comparing a known digest. If another system hashes a file, a binary buffer, UTF-16 text, or normalized text, its result is not directly comparable to this UTF-8 text digest unless the exact input bytes match.
Choosing among the SHA options shown here
SHA-256, SHA-384, SHA-512
These are SHA-2 family digests. Choose the algorithm required by the protocol, checksum, API, test fixture, or system you are comparing against; a longer digest is not interchangeable with a shorter one.
SHA-1 is a compatibility choice
SHA-1 has known collision weaknesses. Its presence here is for reproducing legacy values, not as a recommendation for new signatures, certificates, or adversarial integrity checks.
A matching digest answers a narrow question
If two independently produced digests match, that is strong evidence that the same bytes were hashed with the same algorithm. It does not by itself prove who created those bytes. Authenticity normally needs a keyed construction such as HMAC or a digital signature, depending on the protocol.
Password storage is another separate problem. Fast general-purpose SHA functions are intentionally cheap to compute, which is the opposite of what password verification needs after a database leak. Password verifiers should use a salted, purpose-built password hashing scheme with an appropriate cost factor.
Reference points for implementation work
Browser support and digest names are defined by the Web Crypto API. MDN documentsSubtleCrypto.digest(), including SHA-1, SHA-256, SHA-384, and SHA-512. The algorithms themselves are specified by NIST'sSecure Hash Standard. NIST is transitioning away from SHA-1 for cryptographic protection, which is why SHA-1 is labeled as a legacy comparison option here.
