Method Detail

fromPem

public static <T> T fromPem(com.google.common.io.InputSupplier<? extends InputStream> supplier,
            Pems.PemProcessor<T> processor)
                 throws IOException

Returns the object of generic type T that is pem encoded in the supplier.

Parameters:

supplier - the input stream factory

marker - header that begins the PEM block

processor - how to parser the object from a byte array

Returns:

the object of generic type T which was PEM encoded in the stream

Throws:

IOException - if an I/O error occurs

privateKeySpec

public static KeySpec privateKeySpec(com.google.common.io.InputSupplier<? extends InputStream> supplier)
                              throws IOException

Returns the RSAPrivateKeySpec that is pem encoded in the supplier.

Parameters:

supplier - the input stream factory

Returns:

the RSAPrivateKeySpec which was PEM encoded in the stream

Throws:

IOException - if an I/O error occurs

privateKeySpec

public static KeySpec privateKeySpec(String pem)

Executes privateKeySpec(InputSupplier) on the string which contains an encoded private key in PEM format.

Parameters:

pem - private key in pem encoded format.

See Also:

Parameters:

supplier - the input stream factory

Returns:

the KeySpec which was PEM encoded in the stream

Throws:
