Detailed Description

Private ECC key material encoded for transmission.

To be used only for Edx25519 signatures. An initial key corresponds to data from the key expansion and clamping in the EdDSA key generation.

Field Documentation

a

unsigned char GNUNET_CRYPTO_Edx25519PrivateKey::a[256/8]

a is a value mod n, where n has at most 256 bits.

It is the first half of the seed-expansion of EdDSA and will be clamped.

b

unsigned char GNUNET_CRYPTO_Edx25519PrivateKey::b[256/8]

b consists of 32 bytes which where originally the lower 32bytes of the key expansion.

Subsequent calls to derive_private will change this value, too.
