Package-Level Type Names (total 23, in which 8 are exported)

	/* sort exporteds by: alphabet | popularity */
	 type BitString (struct)
		BitString is the structure to use when you want an ASN.1 BIT STRING type. A
		bit string is padded up to the nearest byte in memory and the number of
		valid bits is recorded. Padding bits will be zero.

		Fields (total 2, both are exported)
			BitLength int
				// length in bits.

			Bytes []byte
				// bits packed into bytes.

		Methods (total 2, both are exported)
			( BitString) At(i int) int
				At returns the bit at the given index. If the index is out of range it
				returns 0.

			( BitString) RightAlign() []byte
				RightAlign returns a slice where the padding bits are at the beginning. The
				slice may share memory with the BitString.

Package-Level Functions (total 52, in which 4 are exported)

	 func Marshal(val any) ([]byte, error)
		Marshal returns the ASN.1 encoding of val.
		
		In addition to the struct tags recognised by Unmarshal, the following can be
		used:
		
			ia5:         causes strings to be marshaled as ASN.1, IA5String values
			omitempty:   causes empty slices to be skipped
			printable:   causes strings to be marshaled as ASN.1, PrintableString values
			utf8:        causes strings to be marshaled as ASN.1, UTF8String values
			utc:         causes time.Time to be marshaled as ASN.1, UTCTime values
			generalized: causes time.Time to be marshaled as ASN.1, GeneralizedTime values

	 func MarshalWithParams(val any, params string) ([]byte, error)
		MarshalWithParams allows field parameters to be specified for the
		top-level element. The form of the params is the same as the field tags.

	 func Unmarshal(b []byte, val any) (rest []byte, err error)
		Unmarshal parses the DER-encoded ASN.1 data structure b
		and uses the reflect package to fill in an arbitrary value pointed at by val.
		Because Unmarshal uses the reflect package, the structs
		being written to must use upper case field names. If val
		is nil or not a pointer, Unmarshal returns an error.
		
		After parsing b, any bytes that were leftover and not used to fill
		val will be returned in rest. When parsing a SEQUENCE into a struct,
		any trailing elements of the SEQUENCE that do not have matching
		fields in val will not be included in rest, as these are considered
		valid elements of the SEQUENCE and not trailing data.
		
		An ASN.1 INTEGER can be written to an int, int32, int64,
		or *big.Int (from the math/big package).
		If the encoded value does not fit in the Go type,
		Unmarshal returns a parse error.
		
		An ASN.1 BIT STRING can be written to a BitString.
		
		An ASN.1 OCTET STRING can be written to a []byte.
		
		An ASN.1 OBJECT IDENTIFIER can be written to an
		ObjectIdentifier.
		
		An ASN.1 ENUMERATED can be written to an Enumerated.
		
		An ASN.1 UTCTIME or GENERALIZEDTIME can be written to a time.Time.
		
		An ASN.1 PrintableString, IA5String, or NumericString can be written to a string.
		
		Any of the above ASN.1 values can be written to an interface{}.
		The value stored in the interface has the corresponding Go type.
		For integers, that type is int64.
		
		An ASN.1 SEQUENCE OF x or SET OF x can be written
		to a slice if an x can be written to the slice's element type.
		
		An ASN.1 SEQUENCE or SET can be written to a struct
		if each of the elements in the sequence can be
		written to the corresponding element in the struct.
		
		The following tags on struct fields have special meaning to Unmarshal:
		
			application specifies that an APPLICATION tag is used
			private     specifies that a PRIVATE tag is used
			default:x   sets the default value for optional integer fields (only used if optional is also present)
			explicit    specifies that an additional, explicit tag wraps the implicit one
			optional    marks the field as ASN.1 OPTIONAL
			set         causes a SET, rather than a SEQUENCE type to be expected
			tag:x       specifies the ASN.1 tag number; implies ASN.1 CONTEXT SPECIFIC
		
		When decoding an ASN.1 value with an IMPLICIT tag into a string field,
		Unmarshal will default to a PrintableString, which doesn't support
		characters such as '@' and '&'. To force other encodings, use the following
		tags:
		
			ia5     causes strings to be unmarshaled as ASN.1 IA5String values
			numeric causes strings to be unmarshaled as ASN.1 NumericString values
			utf8    causes strings to be unmarshaled as ASN.1 UTF8String values
		
		If the type of the first field of a structure is RawContent then the raw
		ASN1 contents of the struct will be stored in it.
		
		If the name of a slice type ends with "SET" then it's treated as if
		the "set" tag was set on it. This results in interpreting the type as a
		SET OF x rather than a SEQUENCE OF x. This can be used with nested slices
		where a struct tag cannot be given.
		
		Other ASN.1 types are not supported; if it encounters them,
		Unmarshal returns a parse error.

	 func UnmarshalWithParams(b []byte, val any, params string) (rest []byte, err error)
		UnmarshalWithParams allows field parameters to be specified for the
		top-level element. The form of the params is the same as the field tags.

		in the given Value.
