Types ¶
type MagicNumber ¶
type MagicNumber uint32
const ( DELTA_MAGIC MagicNumber = 0x72730236 // A signature file with MD4 signatures. // // Backward compatible with librsync < 1.0, but strongly deprecated because // it creates a security vulnerability on files containing partly untrusted // data. See <https://github.com/librsync/librsync/issues/5>. MD4_SIG_MAGIC MagicNumber = 0x72730136 // A signature file using the BLAKE2 hash. Supported from librsync 1.0. BLAKE2_SIG_MAGIC MagicNumber = 0x72730137 )
