Active Directory Federation Services (AD FS) (AD FS) podepisuje své tokeny do Microsoft Azure Active Directory, aby se zajistilo, že je nelze úmyslně The file sha2prog.c is a simple program that accepts input from either STDIN or reads one or more files specified on the command line, and then generates the specified hash (either SHA-224, SHA-256, SHA-384, SHA-512, any combination thereof, or all four hashes at once). 2021. 2. 23.

I have been looking for a SHA-256 implementation in C with no dependencies (preferably self-contained in a single C-file) with a permissive license but found none to my liking. Since the Wikipedia pseudo-code looked extremely well-specified, and since generating test vectors is so easy with sha256sum , I decided to make my own implementation

Let’s step through an example of SHA-256. The hash is used as a unique value of fixed size representing a large amount of data. Hashes of two sets of data should match if and only if the corresponding data also matches. Small changes to the data result in large unpredictable changes in the hash. The hash size for the SHA256 algorithm is 256 bits. I have been looking for a SHA-256 implementation in C with no dependencies (preferably self-contained in a single C-file) with a permissive license but found none to my liking.

C++ sha256 function SHA-256 is the most popular hash function in the SHA-2 family at the time of writing. It provides 128 bits of security for digital signatures and hash-only applications (SHA-1 provides only 80 bits). Remember that while MD5 and SHA-1 are both popular hash functions, MD5 is considered completely broken, SHA-1 is considered weak.

SHA-256 is a secure hash algorithm for computing a condensed representation of an electronic message. Refer to FIPS 180-4 for more details.
