The reason is that dash is used as a part of the name of certain algorithms. Once dm-crypt starts using the givcrypt interface instead of its own IV generators, we can get away with just a single algorithm string, of the form geniv(mode(block-cipher)) Obviously stream ciphers would just be geniv(stream-cipher) So when that happens we can just use the format "-string" as that's an invalid specification in the current format. Of course we'd continue to support the current format as well which can coexist with the new format forever.
