SSH public key fingerprint calculation
Validate common OpenSSH public key encapsulation and calculate SHA256 fingerprint.
It is only processed in the browser, not uploading or saving. Leaving the page will be cleared; the calculation can also be cleared and the result can be discarded. Do not enter other people's credentials or private keys.
SSH public key fingerprint calculation User manual
- Fill in the parameters or select the file according to the form, and check the unit and format first.
- Check the SHA256 fingerprints of the SSH-ED25519 public key.
- Click the processing button to view the results, you can copy or download and save.
Calculation method and processing rules
Read the ssh binary field, check the declaration algorithm and the internal type, and calculate the summary according to the original public key block.
scope of use
Support ED25519, RSA and three NIST ECDSAs; only check the package and length, and do not prove that the key is trustworthy or mathematically safe. Private keys are not accepted.
Will the input content be saved on the server?
This tool handles input in the browser, and does not upload files or form content. Typing practice scores are only saved in the native browser.
Why may the result be different from other tools?
Support ED25519, RSA and three NIST ECDSAs; only check the package and length, and do not prove that the key is trustworthy or mathematically safe. Private keys are not accepted. Please compare the input unit, rounding method, applicable rules and data version first.
