Method Detail

toDecryptedText

public static String toDecryptedText(String aText)

Decrypt the given text in case it has the prefix identifying the text as being encrypted, else the plain text is returned and a warning is printed out that the passed text is not encrypted (just the first two or three chars or zero chars are shown depending on the length of the text). ------------------------------------------------------------------------- Attention: A unique system ID is used for decryption. Decryption with this method will only work on the same system used for encryption via toEncryptedText(String)! ------------------------------------------------------------------------- This method is most useful for encrypting passwords or authentication credentials in configuration files on live servers to provide at least a minimum of security.

Parameters:

aText - The text being decrypted.

Returns:

The decrypted text.

toDecryptedText

public static String toDecryptedText(String aText,
                                     String aPassPharse)

Decrypt the given text in case it has the prefix identifying the text as being encrypted, else the plain text is returned and a warning is printed out that the passed text is not encrypted (just the first two or three chars or zero chars are shown depending on the length of the text).

Parameters:

aText - The text being decrypted.

aPassPharse - The pass phrase for decrypting.

Returns:

The decrypt

toEncryptedText

public static String toEncryptedText(String aText)

Encrypts the given text and prepends a prefix identifying the text as being encrypted. ------------------------------------------------------------------------- Attention: A unique system ID is used for encryption. Decryption with the toDecryptedText(String) method will only work on the same system used for encryption via this method! ------------------------------------------------------------------------- This method is most useful for encrypting passwords or authentication credentials in configuration files on live servers to provide at least a minimum of security.

Parameters:

aText - The text to be encrypted.

Returns:

The encrypted text with the encryption identifier prefixed.

toEncryptedText

public static String toEncryptedText(String aText,
                                     String aPassPhrase)

Encrypts the given text and prepends a prefix identifying the text as being encrypted.

Parameters:

aText - The text to be encrypted.

aPassPhrase - The pass phrase for the encrypted text.
