ALLOW_PLAINTEXT
Allowed encryption level (settings_pack::allowed_enc_level), expressed as the crypto bitmask the spec puts on the wire: plaintext = 0x01 (MseCrypto.CRYPTO_PLAINTEXT), rc4 = 0x02 (MseCrypto.CRYPTO_RC4), both = 0x03 (MseCrypto.CRYPTO_BOTH). These values intentionally equal libtorrent's enc_level enum (pe_plaintext=1, pe_rc4=2, pe_both=3), so a io.github.yuroyami.kitetorrent.settings.EncLevel value can be passed straight through.
