[][src]Struct sequoia_openpgp::packet::Unknown

pub struct Unknown { /* fields omitted */ }

Holds an unknown packet.

This is used by the parser to hold packets that it doesn't know how to process rather than abort.

This packet effectively holds a binary blob.

A note on equality

Two Unknown packets are considered equal if their tags and their bodies are equal.

Implementations

impl Unknown[src]

pub fn new(tag: Tag, error: Error) -> Self[src]

Returns a new Unknown packet.

pub fn hash_algo_security(&self) -> HashAlgoSecurity[src]

The security requirements of the hash algorithm for self-signatures.

A cryptographic hash algorithm usually has three security properties: pre-image resistance, second pre-image resistance, and collision resistance. If an attacker can influence the signed data, then the hash algorithm needs to have both second pre-image resistance, and collision resistance. If not, second pre-image resistance is sufficient.

In general, an attacker may be able to influence third-party signatures. But direct key signatures, and binding signatures are only over data fully determined by signer. And, an attacker's control over self signatures over User IDs is limited due to their structure.

These observations can be used to extend the life of a hash algorithm after its collision resistance has been partially compromised, but not completely broken. For more details, please refer to the documentation for HashAlgoSecurity.

pub fn tag(&self) -> Tag[src]

Gets the unknown packet's tag.

pub fn set_tag(&mut self, tag: Tag) -> Tag[src]

Sets the unknown packet's tag.

pub fn error(&self) -> &Error[src]

Gets the unknown packet's error.

This is the error that caused parsing or processing to abort.

pub fn set_error(&mut self, error: Error) -> Error[src]

Sets the unknown packet's error.

This is the error that caused parsing or processing to abort.

impl Unknown[src]

This packet implements the unprocessed container interface.

Container packets like this one can contain unprocessed data.

pub fn body(&self) -> &[u8][src]

Gets a reference to the this packet's body.

pub fn set_body(&mut self, data: Vec<u8>) -> Vec<u8>[src]

Sets the this packet's body.
