Method Detail

encrypt

String encrypt(String value)

Encrypts a string.

Parameters:

value - the original string.

Returns:

the encrypted string.

Throws:

IllegalArgumentException - if value is null.

Since:

5.5.0

decrypt

String decrypt(String value)
               throws InvalidEncryptedValueException

Decrypts a string.

Parameters:

value - the encrypted string.

Returns:

the string decrypted.

Throws:

IllegalArgumentException - if value is null.

InvalidEncryptedValueException - if value is incompatible with this cipher (probably was not encrypted by it or is corrupted).

UnsupportedOperationException - if this is a one-way cipher and does not support decryption.

Since:

5.5.0
