 | | Signature Block describes the syntax of a generic signature syntax and a series of cryptosystem-specific formats. |
 | | On the other hand, every signature system goes on to add idiosyncratic information to this structure: crytographic protection (padding, protection of algorithm identifiers), certification-authority dependence (naming, key serial #s), content-dependent modification (how is whitespace hashed in?), and mini-assertions (time of signature, whether signed in hardware/software). |
 | | Signature blocks, assertions, and manifests have each been described in terms of their design, operation, format, and distribution. |
