Constructor Detail

RsaEncrypter

public RsaEncrypter(PublicKey key)

Create a new RsaEncrypter

Parameters:

key - the PublicKey for the encryption

Method Detail

getMode

public AbstractCrypto.Mode getMode()

Specified by:

getMode in class AbstractCrypto

Returns:

if this crypto performs an encrypt or decrypt operation

crypt

public String crypt(String text)

Description copied from interface: Crypto

Perform encrypt or decrypt action

Parameters:

text - the String to crypt

Returns:

the result String

setBase64Options

public void setBase64Options(int options)

Parameters:

options - the Base64Options for encoding

encrypt

public static String encrypt(InputStream pubKeyIs,
                             String input)

Encrypt the given text with a public key

Parameters:

pubKeyIs - the public key input stream

input - the input data

Returns:

the encrypted cipher value

encryptFile

public static void encryptFile(InputStream pubKeyIs,
                               InputStream input,
                               OutputStream output)

Encrypt the incoming property file and copy the resulting data into the output stream.

Parameters:

pubKeyIs - the public key input stream

input - the file input stream

output - the output stream to write the encrypted values

encryptPropertyFile

public static void encryptPropertyFile(InputStream pubKeyIs,
                                       InputStream propertyIs,
