Crate tpm2_protocol

TPM 2.0 Protocol

A library for building and parsing TCG TPM 2.0 protocol messages.

Implementation constraints

1. The use of alloc::* is denied.
2. Minimize unsafe code but can be used for appropriate reasons.
3. Panics are not allowed. For unresolvable scenarios use TpmError::InternalError.
4. Only Rustdoc comments, no inline comments allowed. I.e. only comments that are related on generating documentation are allowed.
5. SPDX and Copyright lines are required and exempt from this rule.
6. Enum variants and struct fields follow idiomatic Rust naming conventions (e.g., PascalCase and snake_case respectively).
7. The string representation for all enums, used for serialization and parsing, must strictly follow the TCG specification’s UPPER_SNAKE_CASE naming (e.g., “TPM_ALG_SHA256”).

Constants

TPM_MAX_COMMAND_SIZE

The maximum size of a TPM command or response buffer.

Traits

TpmBuild

TpmParse

TpmParseTagged

Parses a tagged object from a buffer.

TpmSized

Provides two ways to determine the size of an object: a compile-time maximum and a runtime exact size.

TpmTagged

Types that are composed of a tag and a value e.g., a union.

Functions

build_tpm2b

Builds a TPM2B sized buffer.

parse_tpm2b

Parses a TPM2B sized buffer.

tpm_hash_size

Returns the size of a hash digest in bytes for a given hash algorithm.
