# .shtml format
When you encrypt a file with Seald, it is transformed into an
encrypted file, in the .shtml
format. This format is simply an
HTML (opens new window) file, encapsulating the content of the encrypted file, in the
following format:
<!DOCTYPE html>
<!-- saved from url=(0014)about:internet -->
<html>
<head>
<title>Seald Previewer</title>
<meta charset="utf-8">
<script id="seald_script">
window.sealdBaseUrl = 'https://decrypt.seald.io/'
window.sealdDocumentUID = 'a18384a7-a026-4053-a585-c5428d9fb21f'
window.sealdDocument = 'Fai+xZNqvlFCHPJ4tQ0j...'
</script>
<style>
</style>
</head>
<body>
...
</body>
</html>
The seald_script
script has three properties in key/value format:
sealdBaseUrl
: The link to Seald’s lightweight decryption client.sealdDocumentUID
: Theid
of the crypted file.sealdDocument
: The content of the encrypted file encoded in Base64 (opens new window) format.
