Method Detail

encrypt

public static String encrypt(String plainText,
                             String ksPath,
                             String ksPassword,
                             String certificateAlias)
                      throws Exception

encrypt: Obtain encrypted (and ascii-encoded) value for plaintext specified, null strings are not processed and will be returned as null.

Parameters:

plainText - String representing value to be encrypted

ksPath - String representing file path to jks file

ksPassword - String representing password for jks file as specified by path

certificateAlias - String naming the alias of certificate in keystore file

Returns:

String representing encrypted format, null is returned if a null is passed in.

Throws:

Exception - when underlying funtion fails

decrypt

public static String decrypt(String cipherText,
                             String ksPath,
                             String ksPassword,
                             String certificateAlias,
                             String certificatePassword)
                      throws Exception

decrypt: Obtain plain ascii text for encrypted ciphertext specified. Null strings are not processed and will be returned as received. Empty strings will be encoded/encrypted.

Parameters:

cipherText - String representing value to be decrypted

ksPath - String representing file path to jks file

ksPassword - String representing password for jks file as specified by path

certificateAlias - String naming the alias of certificate in keystore file

certificatePassword - String representing password for the certificate's private key

Returns:

String representing the decrypted format of the received string. Null is returned when a null is received.

Throws:

Exception - when underlying funtion fails

decrypt

public static String decrypt(String cipherText,
                             String ksPath,
                             String ksPassword,
                             String certificateAlias)
                      throws Exception

decrypt: Obtain plain ascii text for encrypted ciphertext specified. This method uses the same password for the keystore file and for accessing the private key. Null strings are not processed and will be returned as received. Empty strings will be encoded/encrypted.

Parameters:

cipherText - String representing value to be decrypted

ksPath - String representing file path to jks file

ksPassword - String representing password for jks file as specified by path

certificateAlias - String naming the alias of certificate in keystore file

Returns:

String representing the decrypted format of the received string. Null is returned when a null is received.

Throws:

Exception - when underlying funtion fails
