Method Details

encrypt

public String encrypt(String plainText)

Encrypts the provided plain text using the specified encryption algorithm.

This method uses a SecretKeySpec generated by getKey() to initialize a Cipher in encryption mode. The plain text is then encrypted and encoded in Base64 for safe storage or transmission.

Parameters:

plainText - the text to be encrypted

Returns:

the encrypted text, encoded in Base64; returns the plain text if encryption fails

decrypt

public String decrypt(String encryptedText)

Decrypts the provided encrypted text using the specified encryption algorithm.

This method first decodes the Base64-encoded encrypted text and then uses a SecretKeySpec generated by getKey() to initialize a Cipher in decryption mode. The decrypted bytes are converted back into a UTF-8 encoded string and returned as the original plain text.

Parameters:

encryptedText - the Base64-encoded encrypted text to be decrypted

Returns:

the decrypted plain text; returns the original encrypted text if decryption fails
