Generate SHA-512 checksums for high-security integrity verification. Client-side only — your input never leaves your browser.
SHA-512 is part of the SHA-2 family, producing a 512-bit (64-byte) output. It offers a larger security margin than SHA-256 and is faster than SHA-256 on 64-bit hardware due to native 64-bit operations.
Both SHA-512 and SHA-256 are considered cryptographically secure. SHA-512 produces a longer hash and is marginally faster on 64-bit CPUs. Use SHA-256 for compatibility with most systems; use SHA-512 when longer hash outputs are required.
SHA-512 Hash Generator exists to compute SHA-512 when the publisher or protocol asked for SHA-512 rather than SHA-256. It is not a second copy of the tool homepage. The homepage introduces the whole product. This page stays on one job so a search for that job lands on instructions you can follow without hunting through other tabs. Read the result on this page against the input you actually used. A screenshot without the input is not evidence. If the result surprises you, change one thing and run it again before you change your VPN, browser, or server config.
Work through SHA-512 Hash Generator in order. 1. Confirm the label says SHA-512. 2. Hash the same bytes you were given. 3. Expect a longer hex string than SHA-256. 4. Do not compare a SHA-512 digest to a SHA-256 digest. Write down the input and the output together. When you ask someone for help, send both. Repeat the same input once. A stable tool returns the same answer. If it does not, the input changed or the page is talking to a different network path than you think.
Longer is not a password store. Use bcrypt for passwords. Some tools print SHA-512/256, which is a different length. Read the label. A newline still changes the result. Treat the output as a measurement, then decide. RookVPN does not log the contents of a client-side tool, and a measurement is not a promise that every other app on the device behaves the same way. Compare a second path when the decision matters: a terminal command, another browser, or the matching guide linked below.
Example: the checksum file says SHA512 and the hex is 128 characters. You paste the file hash from this page and compare. If you hashed on the SHA-256 page, the lengths will not match and that is not a corrupt download. Switch pages and hash again.
After you finish SHA-512 Hash Generator, open the SHA-256 page only when the publisher printed SHA-256 if the next question is different from the one this page answers. Stay here if you are still on the same job. Extra pages help only when they answer a new question, such as a different algorithm, a different leak channel, or a different file type. The documentation link on this page is the long form of the same workflow, including the checks that do not fit in the tool UI.
SHA-512 has a larger output and security margin, but both are considered secure against all known attacks. For most practical purposes, SHA-256 and SHA-512 offer equivalent protection.
SHA-512 is used in TLS certificates, Linux password hashing (SHA-512-crypt), and applications requiring longer hash outputs for additional collision resistance.
128 hex characters for SHA-512.
Both are fine for integrity. Use the one that was published.
No.
