Error validating the digital signature of the updated manifest
Customers are more and more requesting agencies of liner companies to issue E-Bills of Lading, electronic invoices, electronic documents, so that transaction costs can be minimized. An electronic signature is the digitized image of a hand written signature.So if you sign a document, the scanned image of this signature, when attached to the document serves the same purpose as that of the manual signature in the document.In the Container Shipping Lines industry the number of documents which may need authorized signature varies from Bill of Lading, Invoices, Receipt, Customs Manifest etc.The number of documents which needs a signature creates a huge task for the authorized signatory and can in many times result in bottlenecks to the release of documents to the consignee or shippers.If no suitable manifest is found in the manifest list, the registry will return a 404 error.One of the challenges in rewriting manifests to the old format is that the old format involves an image configuration for each layer in the manifest, but the new format only provides one image configuration.Its use is optional, and relatively few images will use one of these manifests.
If the object that would otherwise be returned is a manifest list, the registry will look up the appropriate manifest for the amd64 platform and linux OS, rewrite that manifest into the old format if necessary, and return the result to the client.Digital Signature technology is based on Public Key Infrastructure (PKI), where the cryptography algorithm generates two keys that are linked, one for public and the other for private.To create a digital signature, the signing application creates a one-way hash (algorithm that turns signatures into a fixed string of digits) of the electronic data to be signed. This encrypted hash and the algorithm comprises the Digital Signature.Matching decrypted hash means that the data has not changed since it was signed and if the decrypted hash is not the same, it means that the data has changed or been tampered with, or the signatures was created with a private key that does not correspond to the public key of the signer. QR code is similar to the bar-code system which is a machine readable optical label that contains information about the item to which it is attached.
