Class: Cipher Instances of the Cipher class are used to encrypt data. The class can be used in one of two ways: As a stream that is both readable and writable, where plain unencrypted data is written to produce encrypted data on the readable side, or Using the cipher.update() and cipher.final() methods to produce the encrypted data. The crypto.createCipher() or crypto.createCipheriv() methods are used to create Cipher instances. Cipher objects are not to be created directly using the new key

child.stdout <Stream> A Readable Stream that represents the child process's stdout. If the child was spawned with stdio[1] set to anything other than 'pipe', then this will be undefined. child.stdout is an alias for child.stdio[1]. Both properties will refer to the same value.

child.stdio <Array> A sparse array of pipes to the child process, corresponding with positions in the stdio option passed to child_process.spawn() that have been set to the value 'pipe'. Note that child.stdio[0], child.stdio[1], and child.stdio[2] are also available as child.stdin, child.stdout, and child.stderr, respectively. In the following example, only the child's fd 1 (stdout) is configured as a pipe, so only the parent's child.stdio[1] is a stream, all other values in the array
