Data Fields
uint8_t	seckey [ED25519_SECKEY_LEN]

Detailed Description

An Ed25519 secret key

Field Documentation

seckey

uint8_t seckey[ED25519_SECKEY_LEN]

Note that we store secret keys in an expanded format that doesn't match the format from standard ed25519. Ed25519 stores a 32-byte value k and expands it into a 64-byte H(k), using the first 32 bytes for a multiplier of the base point, and second 32 bytes as an input to a hash function for deriving r. But because we implement key blinding, we need to store keys in the 64-byte expanded form.
