MD5_CTX
MD5 context
- array<byte> buffer
- input buffer
- array<int> count
- number of bits, modulo 2^64 (lsb first)
- array<int> state
- state (ABCD)
xURL
a better URL structure that contains all elements
- string hash
- the part after the #, without the leading #
- string hostname
- the hostname
- string location
- the location field, all from the hostname up to the query or hash string, includes leading /
- string password
- possible password that was in the url
- int port
- the port number specified in the URL
- string protocol
- protocol used, like http://, https://, ftp://. But without the '://' part. (ignore the space between the two slashes, it's required because of a bug in UE2)
- string query
- the part after the ?, without the leading ?
- string username
- username that was provided in the URL
Functions
- int AdvSplit(string input, string delim, out array<string> elm, optional string quoteChar )
- Split a string with quotes, quotes may appear anywhere in the string, escape the quote char with a \ to use a literal.
Qoutes are removed from the result, and escaped quotes are used as normal quotes. - array<string> Base64Decode(array<string> indata )
- Decode a base64 encoded string
- array<string> Base64Encode(array<string> indata, out array<string> B64Lookup )
- base64 encode an input array
- Base64EncodeLookupTable(out array<string> LookupTable )
- Generate the base 64 encode lookup table
- string basename(string filename )
- get the base filename
- int daysInYear(int year )
- returns the number of days in a year
- string DecToHex(int dec, int size )
- convert a decimal to hexadecimal notation
- string dirname(string filename )
- get the dirname of a filename, with traling slash
- int getPortByProtocol(string protocol )
- return the default port based on the protocol
- int HexToDec(string hexcode )
- convert a hexadecimal number to the integer counterpart
- string HTTPResponseCode(int code )
- return the description of a HTTP response code
- bool isLeapYear(int year )
- returns if year is a leap year
- int leapsThruEndOf(int y )
- Logf(name Comp, coerce string message, optional int level, optional coerce string Param1, optional coerce string Param2 )
- Write a log entry
- MD5Decode(out array<int> output, array<byte> input, int len )
- MD5Encode(out array<byte> output, array<int> input, int len )
- MD5Final(out array<byte> digest, out MD5_CTX context )
- finalize the MD5 context
- MD5Init(out MD5_CTX context )
- initialize the MD5 context
- MD5Move(string src, int srcindex, out array<byte> buffer, int bufindex, int len )
- string MD5String(string str )
- return the MD5 of the input string
- string MD5StringArray(array<string> stra, optional string Concat )
- Return the MD5 of the input string array. Concat is added after each line.
- MD5Transform(out array<int> Buf, array<byte> block )
- MD5Update(out MD5_CTX Context, string Data, int inputLen )
- update MD5 context
- bool parseUrl(string inURL, out xURL outURL )
- parses the inURL to an xURL structure, return true when succesful
- string RawUrlDecode(string instring, optional bool bIgnorePlus )
- This will decode URL encoded elements. If bIgnorePlus is set to true '+' will not be changed to a space
- string RawUrlEncode(string instring )
- Encode special characters, you should not use this function, it's slow and not secure, so try to avoid it.
This is replace the following characters: ";", "/", "?", ":", "@", "&", "=", "+", ",", "$" and " " - ReplaceChar(out string instring, string from, string to )
- replace part of a string
- int ROTATE_LEFT(int x, int n )
- int stringToTimestamp(string datestring, optional int TZoffset )
- Parse a string to a timestamp
The date string is formatted as: Wdy, DD-Mon-YYYY HH:MM:SS GMT
TZoffset is the local offset to GMT
- int timestamp(int year, int mon, int day, int hour, int min, int sec )
- Create a UNIX timestamp.
Warning: Assumes info is passed in GMT. So make sure you correct the timezone if you are going to send a timestamp generated with this function to an other server. - DateTime timestampToDatetime(int timestamp )
- converts a timestamp to a DateTime record
- string timestampToString(int timestamp, optional string Timezone, optional string format )
- convert a timestamp into a string.
Format can be one of the following strings:
"822", "1123" : RFC 822, updated by RFC 1123 (default), timezone is the TZ CODE
"850", "1036" : RFC 850, obsoleted by RFC 1036, timezone is the TZ CODE
"2822" : RFC 2822, timezone is a +0000 like string
"asctime": ANSI C's asctime() format, timezone is an integer that will increment the hour - string Trim(coerce string S )
- Trim leading and trailing spaces
- float TZtoOffset(string TZ )
- Converts a timezone code to an offset.
- string xURLtoLocation(xURL inURL, optional bool bIncludePassword )
- convert a xURL to a location string, just the location+query+hash
- string xURLtoString(xURL inURL, optional bool bIncludePassword )
- converts a xURL to a string. bIncludePassword defaults to false
