Methods summary

`public Array`	# `decodeBER( String $encoded )` Parse BER-encoding Parse BER-encoding Serves a similar purpose to openssl's asn1parse Parameters `$encoded` `String` $encoded Returns `Array`
`public Array`	# `_decode_ber( String & $encoded, Integer $start = 0 )` Parse BER-encoding (Helper function) Parse BER-encoding (Helper function) Sometimes we want to get the BER encoding of a particular tag. $start lets us do that without having to reencode. $encoded is passed by reference for the recursive calls done for FILE_ASN1_TYPE_BIT_STRING and FILE_ASN1_TYPE_OCTET_STRING. In those cases, the indefinite length is used. Parameters `$encoded` `String` $encoded `$start` `Integer` $start Returns `Array`
`public Array`	# `asn1map( String $decoded, Integer $mapping, mixed $idx = NULL )` ASN.1 Decode ASN.1 Decode Provides an ASN.1 semantic mapping ($mapping) from a parsed BER-encoding to a human readable format. Parameters `$decoded` `String` $encoded `$mapping` `Integer` $start `$idx` Returns `Array`
`public String`	# `encodeDER( String $source, String $mapping )` ASN.1 Encode ASN.1 Encode DER-encodes an ASN.1 semantic mapping ($mapping). Some libraries would probably call this function an ASN.1 compiler. Parameters `$source` `String` $source `$mapping` `String` $mapping Returns `String`
`public String`	# `_encode_der( String $source, String $mapping, Integer $idx = NULL )` ASN.1 Encode (Helper function) ASN.1 Encode (Helper function) Parameters `$source` `String` $source `$mapping` `String` $mapping `$idx` `Integer` $idx Returns `String`
`public String`	# `_encodeLength( Integer $length )` DER-encode the length DER-encode the length DER supports lengths up to (28)127, however, we'll only support lengths up to (28)4. See X.690 § 8.1.3 for more information. Parameters `$length` `Integer` $length Returns `String`
`public String`	# `_decodeTime( String $content, Integer $tag )` BER-decode the time BER-decode the time Called by _decode_ber() and in the case of implicit tags asn1map(). Parameters `$content` `String` $content `$tag` `Integer` $tag Returns `String`
`public`	# `setTimeFormat( String $format )` Set the time format Set the time format Sets the time / date format for asn1map(). Parameters `$format` `String` $format
`public`	# `loadOIDs( Array $oids )` Load OIDs Load OIDs Load the relevant OIDs for a particular ASN.1 semantic mapping. Parameters `$oids` `Array` $oids
`public`	# `loadFilters( Array $filters )` Load filters Load filters See File_X509, etc, for an example. Parameters `$filters` `Array` $filters
`public String`	# `_string_shift( String & $string, optional $index = 1 )` String Shift String Shift Inspired by array_shift Parameters `$string` `String` $string `$index` `optional` Integer $index Returns `String`
