Encode a string using algorithm specified in web.xml and return the resulting encrypted password. If exception, the plain credentials string is returned

参数：

password - Password or other credentials to use in authenticating this username

algorithm - Algorithm used to do the digest

返回：

encypted password based on the algorithm.

encodeString

public static String encodeString(String str)

Encode a string using Base64 encoding. Used when storing passwords as cookies. This is weak encoding in that anyone can use the decodeString routine to reverse the encoding.

参数：

str -

返回：

String

decodeString

public static String decodeString(String str)

Decode a string using Base64 encoding.

参数：

str -

返回：

String
