Detailed Description

A collection for working with certificates.

These helpers are usefully when working with certificates OpenSSL APIs. For example, when dealing with JWKS (JSON Web Key Set)[https://tools.ietf.org/html/rfc7517] you maybe need to extract the modulus and exponent of an RSA Public Key.

Function Documentation

◆ bn2raw()

std::string jwt::helper::bn2raw ( const BIGNUM * bn )

inline

Convert a OpenSSL BIGNUM to a std::string

Parameters

bn	BIGNUM to convert

Returns: bignum as string

◆ convert_base64_der_to_pem() [1/4]

std::string jwt::helper::convert_base64_der_to_pem ( const std::string & cert_base64_der_str )

inline

Convert the certificate provided as base64 DER to PEM.

This is useful when using with JWKs as x5c claim is encoded as base64 DER. More info (here)[https://tools.ietf.org/html/rfc7517#section-4.7]

Parameters

cert_base64_der_str String containing the certificate encoded as base64 DER

Exceptions

rsa_exception if an error occurred

◆ convert_base64_der_to_pem() [2/4]

template<typename Decode >

std::string jwt::helper::convert_base64_der_to_pem	(	const std::string &	cert_base64_der_str,
		Decode	decode
	)

Convert the certificate provided as base64 DER to PEM.

This is useful when using with JWKs as x5c claim is encoded as base64 DER. More info (here)[https://tools.ietf.org/html/rfc7517#section-4.7]

Template Parameters

Decode is callabled, taking a string_type and returns a string_type. It should ensure the padding of the input and then base64 decode and return the results.

Parameters

cert_base64_der_str	String containing the certificate encoded as base64 DER
decode	The function to decode the cert

Exceptions

rsa_exception if an error occurred
