Detailed Description

Public key wrapper for signature verification.

The PubKey class wraps a public key and implements signature verification. It only supports RSA keys and the RSA-SHA256 signature algorithm.

Constructor & Destructor Documentation

PubKey()

libcamera::PubKey::PubKey

(

Span< const uint8_t >

key

)

Construct a PubKey from key data.

Parameters

[in]

key

Key data encoded in DER format

Member Function Documentation

isValid()

bool libcamera::PubKey::isValid ( ) const

inline

Check is the public key is valid.

Returns

True if the public key is valid, false otherwise

verify()

bool libcamera::PubKey::verify	(	Span< const uint8_t >	data,
		Span< const uint8_t >	sig
	)		const

Verify signature on data.

Parameters

[in]	data	The signed data
[in]	sig	The signature

Verify that the signature sig matches the signed data for the public key. The signture algorithm is hardcoded to RSA-SHA256.

Returns

True if the signature is valid, false otherwise
