Algorithms

The algorithm identifiers the PIGI envelope's Algorithm byte can carry, and what each one means.

Current SDK format generation. This page documents the envelope format the mintBlue SDK writes today. The open SDX Protocol specifies a later generation of this format; the two are not wire-compatible. Read the open specification

Generations sets out which of the two documents applies to the code you installed.

The Algorithm field of the envelope format is one byte, and this table is what that byte means. It publishes the identifiers, not the primitives behind them: the normative description of the envelope model and its cryptography is the specification linked above.

0'aes-256-cbc:lzma:cbor'The filename, filetype and filecontent are placed in an array and encoded with CBOR. The resulting bytes are then compressed with LZMA. The resulting bytes are then encrypted with AES-256-CBC

Envelope Format

The PIGI envelope format version 0, its six fields with sizes and offsets, and the struct definition that reads them.

Examples

Two complete applications built on the SDK, small enough to read in one sitting and structured so you can lift pieces out of them.
