// Strings.
//
// ASN.1 contains a myriad of string types, as well as types that contain data
// that may be encoded into a string. This library uses a single type,
// |ASN1_STRING|, to represent most values.

// An asn1_string_st (aka |ASN1_STRING|) represents a value of a string-like
// ASN.1 type. It contains a type field, and a byte string data field with a
// type-specific representation.
//
// When representing a string value, the type field is one of
// |V_ASN1_OCTET_STRING|, |V_ASN1_UTF8STRING|, |V_ASN1_NUMERICSTRING|,
// |V_ASN1_PRINTABLESTRING|, |V_ASN1_T61STRING|, |V_ASN1_VIDEOTEXSTRING|,
// |V_ASN1_IA5STRING|, |V_ASN1_GRAPHICSTRING|, |V_ASN1_ISO64STRING|,
// |V_ASN1_VISIBLESTRING|, |V_ASN1_GENERALSTRING|, |V_ASN1_UNIVERSALSTRING|, or
// |V_ASN1_BMPSTRING|. The data contains the byte representation of of the
// string.
//
// When representing a BIT STRING value, the type field is |V_ASN1_BIT_STRING|.
// The data contains the encoded form of the BIT STRING, including any padding
// bits added to round to a whole number of bytes, but excluding the leading
// byte containing the number of padding bits. The number of padding bits is
// encoded in the flags field. See |ASN1_STRING_FLAG_BITS_LEFT| for details. For
// example, DER encodes the BIT STRING {1, 0} as {0x06, 0x80 = 0b10_000000}. The
// |ASN1_STRING| representation has data of {0x80} and flags of
// ASN1_STRING_FLAG_BITS_LEFT | 6.
//
// When representing an INTEGER or ENUMERATED value, the data contains the
// big-endian encoding of the absolute value of the integer. The sign bit is
// encoded in the type: non-negative values have a type of |V_ASN1_INTEGER| or
// |V_ASN1_ENUMERATED|, while negative values have a type of
// |V_ASN1_NEG_INTEGER| or |V_ASN1_NEG_ENUMERATED|. Note this differs from DER's
// two's complement representation.
//
// When representing a GeneralizedTime or UTCTime value, the type field is
// |V_ASN1_GENERALIZEDTIME| or |V_ASN1_UTCTIME|, respectively. The data contains
// the DER encoding of the value. For example, the UNIX epoch would be
// "19700101000000Z" for a GeneralizedTime and "700101000000Z" for a UTCTime.
//
// TODO(davidben): |ASN1_TYPE| additionally uses |ASN1_STRING| to represent
// various other odd cases. It also likes to assume unknown universal tags are
// string types. Make a note here when documenting |ASN1_TYPE|.
//
// |ASN1_STRING| additionally has the following typedefs: |ASN1_BIT_STRING|,
// |ASN1_BMPSTRING|, |ASN1_ENUMERATED|, |ASN1_GENERALIZEDTIME|,
// |ASN1_GENERALSTRING|, |ASN1_IA5STRING|, |ASN1_INTEGER|, |ASN1_OCTET_STRING|,
// |ASN1_PRINTABLESTRING|, |ASN1_T61STRING|, |ASN1_TIME|,
// |ASN1_UNIVERSALSTRING|, |ASN1_UTCTIME|, |ASN1_UTF8STRING|, and
// |ASN1_VISIBLESTRING|. Other than |ASN1_TIME|, these correspond to universal
// ASN.1 types. |ASN1_TIME| represents a CHOICE of UTCTime and GeneralizedTime,
// with a cutoff of 2049, as used in Section 4.1.2.5 of RFC 5280.
//
// For clarity, callers are encouraged to use the appropriate typedef when
// available. They are the same type as |ASN1_STRING|, so a caller may freely
// pass them into functions expecting |ASN1_STRING|, such as
// |ASN1_STRING_length|.
//
// If a function returns an |ASN1_STRING| where the typedef or ASN.1 structure
// implies constraints on the type field, callers may assume that the type field
// is correct. However, if a function takes an |ASN1_STRING| as input, callers
// must ensure the type field matches. These invariants are not captured by the
// C type system and may not be checked at runtime. For example, callers may
// assume the output of |X509_get0_serialNumber| has type |V_ASN1_INTEGER| or
// |V_ASN1_NEG_INTEGER|. Callers must not pass a string of type
// |V_ASN1_OCTET_STRING| to |X509_set_serialNumber|. Doing so may break
// invariants on the |X509| object and break the |X509_get0_serialNumber|
// invariant.
//
// TODO(davidben): This is very unfriendly. Getting the type field wrong should
// not cause memory errors, but it may do strange things. We should add runtime
// checks to anything that consumes |ASN1_STRING|s from the caller.
