This generated hash value is then rendered in a hexadecimal format number which is 40 digits long. This generated hash value is known as a message digest. It is a cryptographic hash function that will take input and it produces a 160-bit hash value. SHA-1 also referred to as the Secure Hash Algorithm.

The SHA keys are the unique identity of your application. If you want to add external APIs from Google such as Maps and other external features inside your app, then you have to add your key to Google’s console. In Android SHA1, MD5 and SA-256 keys are very important. It is a secure key that is used to store very important data. SHA1, MD5, and SHA-256 are cryptographic functions that will convert your input to 160 bit (20 bytes) value.
