XMPPAddress
- the XMPP address.public static java.lang.String parseServer(java.lang.String XMPPAddress)
XMPPAddress
- the XMPP address.public static java.lang.String parseResource(java.lang.String XMPPAddress)
XMPPAddress
- the XMPP address.public static java.lang.String parseBareAddress(java.lang.String XMPPAddress)
XMPPAddress
- the XMPP address.public static java.lang.String escapeForXML(java.lang.String string)
string
- the string to escape.public static java.lang.String hash(java.lang.String data)
A hash is a one-way function -- that is, given an input, an output is easily computed. However, given the output, the input is almost impossible to compute. This is useful for passwords since we can store the hash and a hacker will then have a very hard time determining the original password.
data
- the String to compute the hash of.public static java.lang.String encodeHex(byte[] bytes)
bytes
- an array of bytes to convert to a hex string.public static java.lang.String encodeBase64(java.lang.String data)
data
- a String to encode.public static java.lang.String encodeBase64(byte[] data)
data
- a byte array to encode.public static java.lang.String encodeBase64(byte[] data, boolean lineBreaks)
data
- The byte arry to encode.lineBreaks
- True if the encoding should contain line breaks and false if it should not.public static java.lang.String encodeBase64(byte[] data, int offset, int len, boolean lineBreaks)
data
- The byte arry to encode.offset
- the offset of the bytearray to begin encoding at.len
- the length of bytes to encode.lineBreaks
- True if the encoding should contain line breaks and false if it should not.public static byte[] decodeBase64(java.lang.String data)
data
- a base64 encoded String to decode.public static java.lang.String randomString(int length)
The specified length must be at least one. If not, the method will return null.
length
- the desired length of the random String to return.Copyright © 2003 Jive Software.
