Method Detail

encodeCharset

@Deprecated
public static String encodeCharset(String str,
                                                String charsetName)

Deprecated. Use

Encodes this String into a sequence of bytes using the named charset, storing the result into a new byte array.

Parameters:

str - target string

charsetName - the name of a supported charset

Returns:

The resultant string

decodeCharset

@Deprecated
public static String decodeCharset(String str,
                                                String charsetName)

Deprecated. Use

Decodes this String into a sequence of bytes using the named charset, storing the result into a new byte array.

Parameters:

str - target string

charsetName - the name of a supported charset

Returns:

The resultant string

encodeBase64

public static String encodeBase64(String str)

Encode a string using Base64 encoding. This is weak encoding in that anyone can use the decodeString routine to reverse the encoding.

Parameters:

str - String to be encoded

Returns:

String encoding result

See Also:

BaseNCodec.encode(byte[])

decodeBase64

public static String decodeBase64(String str)

Decode a string using Base64 encoding.

Parameters:

str - String to be decoded

Returns:

String decoding String

See Also:

BaseNCodec.decode(String)

encodePassword

public static String encodePassword(String password,
                                    String algorithm)
                             throws NoSuchAlgorithmException

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

Parameters:

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

algorithm - Algorithm used to do the digest

Returns:

encrypted password based on the algorithm.

Throws:

NoSuchAlgorithmException - throws No Such Algorithm Exception
