ERXDESCrypter

public ERXDESCrypter()

ERXDESCrypter

public ERXDESCrypter(java.lang.String secretKeyPathFramework,
                     java.lang.String secretKeyPath)

Method Detail

setSecretKeyPathFramework

public void setSecretKeyPathFramework(java.lang.String secretKeyPathFramework)

setSecretKeyPath

public void setSecretKeyPath(java.lang.String secretKeyPath)

defaultSecretKey

protected java.security.Key defaultSecretKey()

Returns the DES java.security.Key found in the key file. The Key is cached once it's found so further hits to the disk are unnecessary. If the key file cannot be found, the method creates a key and writes out a key file.

decrypt

public java.lang.String decrypt(java.lang.String cryptedText)

Base64 decodes and then DES decrypts the passed in string using the secret key returned by secretKey.

Specified by:

decrypt in interface ERXCrypterInterface

Parameters:

cryptedText - the string to decrypt

Returns:

the decrypted string

decrypt

public java.lang.String decrypt(java.lang.String cryptedText,
                                java.security.Key secretKey)

Base64 decodes and then DES decrypts the passed in string using the passed in secret key.

encrypt

public java.lang.String encrypt(java.lang.String clearText)

DES Encrypts and then base64 encodes the passed in String using the secret key returned by secretKey. The base64 encoding is performed to ensure that the encrypted string can be stored in places that don't support extended character sets.

Specified by:

encrypt in interface ERXCrypterInterface

Parameters:

clearText - the text to encrypt

Returns:

an encrypted version of the text

encrypt

public java.lang.String encrypt(java.lang.String clearText,
                                java.security.Key secretKey)

DES Encrypts and then base64 encodes the passed in String using the passed in secret key. The base64 encoding is performed to ensure that the encrypted string can be stored in places that don't support extended character sets.
