{"name":"NorthCloud","active":true} is a valid example.

Base64 is not encryption
Base64 represents bytes with printable characters. Anyone who has an encoded value can decode it.
NorthCloud uses UTF-8, so multilingual text and emoji work as expected.
Open the tool →Why SHA-256 matters
SHA-256 computes a 256-bit fingerprint of input data. Changing a file will almost certainly change its checksum.
A matching hash helps verify an intact download, but does not independently establish the publisher's identity.
Hash a file →Reading browser signals
Time and time zone come from the local device. The network hint uses navigator.onLine: it can be inaccurate and does not check any server's availability.
Use dedicated network diagnostics to test a specific remote address.
Back to home →Where your data goes
The tools operate locally and contain no code that uploads entered text or selected files. Loading a website still exposes network information, including your IP address, to the server.
Consider untrusted browser extensions and avoid entering sensitive secrets without good reason.
Read the policy →HTTPS and safe browsing
HTTPS protects the connection between your browser and the site when certificate verification succeeds. It does not guarantee device security or the safety of browser extensions.
Verify the domain and never dismiss certificate warnings before providing personal information.
