Macros

ngtcp2 crypto library error codes

NGTCP2_CRYPTO_ERR_INTERNAL: NGTCP2_CRYPTO_ERR_INTERNAL indicates an internal error.

NGTCP2_CRYPTO_ERR_UNREADABLE_TOKEN: NGTCP2_CRYPTO_ERR_UNREADABLE_TOKEN indicates that a token is unreadable because it is not correctly formatted; or verifying the integrity protection failed.

NGTCP2_CRYPTO_ERR_VERIFY_TOKEN: NGTCP2_CRYPTO_ERR_VERIFY_TOKEN indicates that a token does not probe the client address; or the token validity has expired; or it contains invalid Connection ID.

NGTCP2_CRYPTO_TOKEN_RAND_DATALEN: NGTCP2_CRYPTO_TOKEN_RAND_DATALEN is the length of random data added to a token generated by ngtcp2_crypto_generate_retry_token() or ngtcp2_crypto_generate_regular_token().

NGTCP2_CRYPTO_TOKEN_MAGIC_RETRY: NGTCP2_CRYPTO_TOKEN_MAGIC_RETRY is the magic byte for Retry token generated by ngtcp2_crypto_generate_retry_token().

NGTCP2_CRYPTO_TOKEN_MAGIC_RETRY2: NGTCP2_CRYPTO_TOKEN_MAGIC_RETRY2 is the magic byte for Retry token generated by ngtcp2_crypto_generate_retry_token2().

NGTCP2_CRYPTO_TOKEN_MAGIC_REGULAR: NGTCP2_CRYPTO_TOKEN_MAGIC_REGULAR is the magic byte for a token generated by ngtcp2_crypto_generate_regular_token().

NGTCP2_CRYPTO_MAX_RETRY_TOKENLEN: NGTCP2_CRYPTO_MAX_RETRY_TOKENLEN is the maximum length of a token generated by ngtcp2_crypto_generate_retry_token().

NGTCP2_CRYPTO_MAX_RETRY_TOKENLEN2: NGTCP2_CRYPTO_MAX_RETRY_TOKENLEN2 is the maximum length of a token generated by ngtcp2_crypto_generate_retry_token2().

NGTCP2_CRYPTO_MAX_REGULAR_TOKENLEN

NGTCP2_CRYPTO_MAX_REGULAR_TOKENLEN is the maximum length: of a token generated by ngtcp2_crypto_generate_regular_token().

quictls specific error codes

NGTCP2_CRYPTO_QUICTLS_ERR_TLS_WANT_X509_LOOKUP: NGTCP2_CRYPTO_QUICTLS_ERR_TLS_WANT_X509_LOOKUP is the error code which indicates that TLS handshake routine is interrupted by X509 certificate lookup. See SSL_ERROR_WANT_X509_LOOKUP error description from SSL_do_handshake().

NGTCP2_CRYPTO_QUICTLS_ERR_TLS_WANT_CLIENT_HELLO_CB: NGTCP2_CRYPTO_QUICTLS_ERR_TLS_WANT_CLIENT_HELLO_CB is the error code which indicates that TLS handshake routine is interrupted by client hello callback. See SSL_ERROR_WANT_CLIENT_HELLO_CB error description from SSL_do_handshake().
