Change Details

{T4954} made a progress, from a viewpoint of underlying crypto operations, for keeping the binary representation intact. It allows stopping bad practice and we identified bugs in libgcrypt and gpg-agent for modifying data silently (see: T4956 and T4964). On the other hand, GnuPG 2.2 and other implementations keep old practice removing leading zeros in Ed25519 signature in the upper layer. Given this situation, when importing, it is good to retain the binary representation of external input key, specifically, the data of the Ed25519 signature.
