2.4.1 PUBLICKEYBLOB

The PUBLICKEYBLOB type is used to export public keys for use with the RSA key exchange algorithm ([RFC8017]) from a receiver to senders for use in sending encrypted messages to that receiver.

bitLen (4 bytes): A 32-bit unsigned number in little-endian format. MUST be the bit length of the RSA modulus, defined as k*8 in the terminology of [RFC8017] section 2.

pubExp (4 bytes): A 32-bit unsigned number in little-endian format. MUST be the public exponent of the key pair, referred to as e in [RFC8017] section 2.

modulus (variable): The RSA modulus, referred to as n in [RFC8017] section 2. This field MUST be encoded in little-endian format. Its length in bits MUST be equal to the value in the bitLen field.
