About ZebraSign
What is ZebraSign?
ZebraSign is a program for creating and verifying ring signatures. This website provides verification, but not signing.
What are Ring Signatures?
A ring signature is a digital signature produced using one private key plus some number of public keys. The resulting message can be proven to have been signed by exactly one of those keyholders, but there is no way to prove which one. This is different from Group Signatures.
How to Use This Website
If you want to verify a ring signature, you can do that here. Copy and paste the entire ring-signed message into the text box, and it will tell you if the identities listed were in fact used to sign the message. That is not sufficient to implicate the people named in the list–for that, you will need to see some endorsement of the identity by those people, for example fingerprints listed on a personal website or twitter bio or similar.
Want More Features?
If you wish verification were easier, or if you want to sign messages, you can download the app.
