/**
 * Pure-PHP ASN.1 Parser
 *
 * PHP version 5
 *
 * ASN.1 provides the semantics for data encoded using various schemes.  The most commonly
 * utilized scheme is DER or the "Distinguished Encoding Rules".  PEM's are base64 encoded
 * DER blobs.
 *
 * \phpseclib3\File\ASN1 decodes and encodes DER formatted messages and places them in a semantic context.
 *
 * Uses the 1988 ASN.1 syntax.
