Cipherinputstream rsa
WebA CipherInputStream is composed of an InputStream and a Cipher so that read () methods return data that are read in from the underlying InputStream but have been additionally processed by the Cipher. The Cipher must be fully initialized before being used by a CipherInputStream. WebApr 16, 2014 · the FileInputStream gives me the encoded key (it is not the problem) but when passed through the CipherInputStream, the data becomes all zeroes. aesKey and aesKeySpec are static variables, privateKey is a valid RSA key.
