Struct KeyInfo

pub struct KeyInfo {
    pub key: Vec<u8>,
    pub salt: Vec<u8>,
    pub info: Vec<u8>,
}

A struct that holds the key information required for key expansion.

The key expansion process is used to derive a new key from the main secret key. Its main purpose is to expand the key to the HMAC algorithm’s block size to avoid padding which can reduce the effort required for a brute force attack.

The KeyInfo struct contains the main secret key, salt for key expansion, and optional application-specific info.

• key field is the main secret key used for signing and verifying data.
• salt field is used for key expansion.
• info field is optional and can be used to provide application-specific information.

The salt and the info fields can help to prevent key reuse and provide additional security.

Fields

key: Vec<u8>

salt: Vec<u8>

info: Vec<u8>
