With Cryptomator 2.0 for iOS Beta, is the vault version 8?

Just wondering as I haven’t seen much documentation for the current beta, what is the vault version? Usually could tell taking a look at the Masterkey, but i’m seeing “version:999” instead of the usual formats we’re used to.

A detailed description will follow but version: 999 is a hint for vault version 8 or later. If you open the vault.cryptomator file of the vault in an text editor and decode the content of this file (which is a JSON Web Token) using e.g. https://jwt.io/ you will find out the vault format, it should look something like this

Header
{
  "kid": "masterkeyfile:masterkey.cryptomator",
  "typ": "JWT",
  "alg": "HS256"
}
Payload
{
  "maxFilenameLen": 220,
  "format": 8,
  "jti": "8f78d520-3bc3-4475-8d9f-349def87c988",
  "cipherCombo": "SIV_CTRMAC"
}

format is the property you’re looking for.

TLDR; Cryptomator 2.0 iOS Beta creates new vaults in vault format 8 but can also handle old formats.
