nl_tokens: Marshal converts a jwk encodec ECDH public key into the form specified in section 4 . 3 . 6 of ANSI X9 . 62 . ( This is the format go - ipfs uses )
pl_tokens: function marshalPublicKey ( jwk ) { const byteLen = curveLengths [ jwk . crv ] return Buffer . concat ( [ Buffer . from ( [ 4 ] ) , // uncompressed point toBn ( jwk . x ) . toArrayLike ( Buffer , 'be' , byteLen ) , toBn ( jwk . y ) . toArrayLike ( <mask> , 'be' , byteLen ) ] , 1 + byteLen * 2 ) }
