This API supports the product infrastructure and is not intended to be used directly from your code. Implements the SGen task. Use the SGen element in your project file to create and execute this task. For usage and parameter information, see SGen Task.
What is a cryptographic hash? A hash (also called a digest, and informally a checksum) is a kind of signature for a stream of data that represents the contents. The closest real-life analog we can think is a tamper-evident seal on a software package: if you open the box (change the file), it's detected.
In computer cryptography, a key is a long sequence of bits used by encryption and decryption algorithms. An encryption algorithm takes the original un-encrypted message, and a key like the above, and alters the original message mathematically based on the key's bits to create a new encrypted message.
