The secret 16 bytes (32 characters) isn't actually a key in the sense that it's used to encrypt and decrypt something. Rather, it's a bit of data (a salt) that is used to alter the result of the digital signature, by changing the input ever-so-slightly, so that only someone who knew the exact secret and the exact payload could have created the signature.

In cryptography, SHA-1 (Secure Hash Algorithm 1) is a cryptographic hash function which takes an input and produces a 160-bit (20-byte) hash value known as a message digest – typically rendered as a hexadecimal number, 40 digits long. MD5 was used for a number of years until it was found to have a security flaw in 2004 which set the stage for SHA-1. Hash algorithms take a variable length input string and reduce it to a typically shorter and fixed length output (160 bits for SHA-1), the goal of which being to provide a unique identifier for that input. They differ in both construction (how the resulting hash is created from the original data) and in the bit-length of the signature. You should think of SHA-2 as the successor to SHA-1, as it is an overall improvement. Primarily, people focus on the bit-length as the important distinction. SHA-1 is a 160-bit hash. Getting your SHA1 key is a little more complicated on a Windows system so, follow along with my steps here: 1) Open Command Prompt by pressing Start+R and typing cmd.exe.. 2) Using Windows Explorer, find where your JDK directory is located (Usually Program Files >> Java) and copy the path.

Mar 08, 2017 · Is it possible to change the default key size & hash algorithm that windows uses to create certificates? For example if I create a file server and log into it through the RDP client, windows will create a self sign cert under Certificates\Remote Desktop\Certificates with the settings: (*I am not concerned with the RDP certificates so much, its any cert that the server creates on its own) key

To generate an API key you require, SHA1 fingerprint of your keystore. Keystore is basically a place where the private keys for your app are kept. In simple words its a certificate generated by user or a program, used for signing an Android app.
