public class ASN1IA5String
extends ASN1VisibleString

Models the abstract concept of the value of ASN.1 type IA5String.

Extends ASN1VisibleString to provide minimal encoding and decoding support needed to model the abstract concept of a value of ASN.1 type IA5String.

Universal class tag assignment is UNIVERSAL 22.

XML ASN.1 type name is IA5String.

No permitted alphabet constraints are enforced on values of this type, as these constraints are left to the application. Characters of this ASN.1 type are treated as opaque, having no structure or meaning, though all characters are represented in a single octet.

Type IA5String specifies single byte, fixed width, restricted character strings. The set of characters that can be used to form values of type IA5String is "restricted" to those defined in the International Register of Coded Character Sets to be Used With Escape Sequences. For these character values, this standard references ISO 646:1991 Information technology - ISO 7-bit coded character set for information interchange directly, though the ASN.1 standards only reference ISO 646:1991 indirectly.

The values of type IA5String represent the same characters as the first one hundered and twenty-eight values of types BMPString, UTF8String, and UniversalString.

The values of the builtin types NumericString, PrintableString, and VisibleString are subsets of the values of type IA5String. In terms of their character values, NumericString is a subset of PrintableString, which is a subset of VisibleString, which is a subset of IA5String.

The values of NumericString are limited to '0123456789' and 'space'. The values of VisibleString include all of the human-readable characters in IA5String, but exclude all of the computer control characters such as 'delete' and 'escape'.

Values of type IA5String are sometimes referred to as the ASCII or US ASCII character set. This may be because IA5String values include characters which look like and which have been assigned the names of the letters in the modern English alphabet. But these values can also be interpreted as coming from the Hawaiian alphabet or from Romaji, a written form of Japanese.

Any meanings assigned to the values of abstract characters defined using ASN.1 depend completely on the observer. No meanings are assigned by the ASN.1 standards. These single-byte values are the most commonly supported characters in Internet standards today, but use of IA5String and its subset types are being replaced by use of a single type UTF8String, which encodes all of the characters of IA5String in a single octet, and supports most of the world's languages.
