Detailed Description

Elliptic curve public key.

From: https://tools.ietf.org/html/rfc5480#section-2.2

The elliptic curve public key (a value of type ECPoint that is an OCTET STRING) is mapped to a subjectPublicKey (a value of type BIT STRING) as follows: the most significant bit of the OCTET STRING value becomes the most significant bit of the BIT STRING value, and so on; the least significant bit of the OCTET STRING becomes the least significant bit of the BIT STRING. Conversion routines are found in Sections 2.3.1 and 2.3.2 of [SEC1].

The first octet of the OCTET STRING indicates whether the key is compressed or uncompressed. The uncompressed form is indicated by 0x04 and the compressed form is indicated by either 0x02 or 0x03 (see 2.3.3 in [SEC1]). The public key MUST be rejected if any other value is included in the first octet.

This implementation assumes that the key is uncompressed.

Member Function Documentation

dump()

void EcPublicKeyCert::dump ( const EccGfpPoint &  pub, std::vector< char > &  v  )

static

Dump to memory.

Dumps the point directly to the vector. Vector is resized.

Definition at line 399 of file cert.cc.

parse()

void EcPublicKeyCert::parse ( const BasePtr &  b, const KeyAlgoType &  algo, EccGfpPoint &  pub  )

static

Parse from a bit string for a specific curve.

Throws exception if string is compressed, or is an invalid point for the curve.

The KeyAlgoType type must be one of the ecdsa types.
