Package org.bouncycastle.asn1

## Class DERIA5String

- java.lang.Object
- - org.bouncycastle.asn1.ASN1Object
  - - org.bouncycastle.asn1.ASN1Primitive
    - - org.bouncycastle.asn1.DERIA5String

- All Implemented Interfaces:
    `ASN1Encodable`, `ASN1String`, `Encodable`
  Direct Known Subclasses:
    `NetscapeRevocationURL`, `VerisignCzagExtension`

      public class DERIA5String
      extends ASN1Primitive
      implements ASN1String

  DER IA5String object - this is a ISO 646 (ASCII) string encoding code points 0 to 127.

  Explicit character set escape sequences are not allowed.

- - ### Constructor Detail

    - #### DERIA5String

          public DERIA5String​(java.lang.String string)

      Basic constructor - without validation.
      Parameters:
        `string` - the base string to use..

    - #### DERIA5String

          public DERIA5String​(java.lang.String string,
                              boolean validate)

      Constructor with optional validation.
      Parameters:
        `string` - the base string to wrap.
        `validate` - whether or not to check the string.
      Throws:
        `java.lang.IllegalArgumentException` - if validate is true and the string contains characters that should not be in an IA5String.

  - ### Method Detail

    - #### getInstance

          public static DERIA5String getInstance​(java.lang.Object obj)

      Return an IA5 string from the passed in object
      Parameters:
        `obj` - a DERIA5String or an object that can be converted into one.
      Returns:
        a DERIA5String instance, or null.
      Throws:
        `java.lang.IllegalArgumentException` - if the object cannot be converted.

    - #### getInstance

          public static DERIA5String getInstance​(ASN1TaggedObject obj,
                                                 boolean explicit)

      Return an IA5 String from a tagged object.
      Parameters:
        `obj` - the tagged object holding the object we want
        `explicit` - true if the object is meant to be explicitly tagged false otherwise.
      Returns:
        a DERIA5String instance, or null.
      Throws:
        `java.lang.IllegalArgumentException` - if the tagged object cannot be converted.

    - #### getString

          public java.lang.String getString()

      Description copied from interface: `ASN1String`
