Method Detail

setMasterHash

void setMasterHash(String masterPassword,

                   boolean overwrite)
            throws IOException

Store a hash based on the given masterpassword and masterSalt in ~/.deltaspike/master.hash

Parameters:

masterPassword -

masterSalt - same masterSalt as later used by the application to decrypt the hash

overwrite - whether an existing passkey file does not get overwritten.

Throws:

IOException - if the master hash file could not be written

IllegalStateException - if a masterhash already exists

encrypt

String encrypt(String cleartext,
               String masterSalt)

Encrypt the given cleartext. We use the masterSalt to access the MasterHash to use as key for encryption

Parameters:

cleartext - to get encrypted

masterSalt - the same as used for setMasterHash(String, String, boolean)

Returns:

the encrypted String to store somewhere

decrypt

String decrypt(String encryptedValue,
               String masterSalt)

Decrypt the given encrypted value. We use the masterSalt to access the MasterHash to use as key for encryption

Parameters:

encryptedValue - to get decrypted

masterSalt - the same as used for setMasterHash(String, String, boolean)
