Snap-revision assertion

The snap-revision assertion is a statement by the store acknowledging the receipt of a snap build and labelling it with a snap revision.

Alongside account, snap-declaration and account-key-assertion assertions, snap-revision_ is bundled within the composite .assert file that accompanies a snap downloaded with the snap download <snap-name> command.

Snap-revision assertion fields

The assertion format is as follows:

type:              snap-revision
authority-id:      <authority account id>
snap-sha3-384:     <sha3-384 digest as url-safe unpadded base64>
developer-id:      <developer account id>
snap-id:           <snap-id>
snap-revision:     <int>
snap-size:         <int>
timestamp:         <UTC datetime>
sign-key-sha3-384: <key id> # Encoded key id of signing key

<signature>                 # Encoded signature

The index is the digest of the snap blob, snap-sha3-384. The store returns the revision assigned to the uploaded snap along other data.

See Assertion format for more details on fields common to most assertions.
