This application creates a unique certificate (called a Non-Fungible Token) that contains a digest of a document or a text to notarize.
This digest is a representation of your document/text as a 64 character string. One can not reconstruct a document with its hash. It is therefore not necessary to disclose this document.
- Hello world! digest is: c0535...9e51a c0535e4be2b79ffd93291305436bf889314e4a3faec05ecffcbb7df31ad9e51a
- I•alreadyknew•it logo digest is: ee250...1da96 ee250506ea3d5948bcccba332df3fa9806c334c967a1deade2b42e9b0cd1da96
You can either notarize a file, a text, or a digest that you have calculated yourself. The digest is computed locally in your browser (no data is sent to our server).
Then you can check any digest here and find out who it belongs to and when it was issued.
