What is this 'SHA-1' for and how do I use it?
Thanks in advance.

Re: SHA-1
Are you referring to the SHA-1 checksum numbers on the download page?
These are so that you can test whether your downloaded zip files are correct as the RPF intended. Sometimes downloads appear to be successful, but problems with the server or your own bandwidth can corrupt the contents.
To test your downloaded images, refer to the Verifying an Image tutorial here.
If your hash pattern (the long number) matches up with the one on the image download page, then you've downloaded the file successfully. If not, then it's best to try and download the image again, or if possible use the Bittorrent download which is more reliable.

Re: SHA-1
SHA-1 is used for cryptography and for checking data integrity.

You might, for example, use it to check that a downloaded RPi disk image is genuine or that it is not corrupted. It might also be used in negotiating a secure connection to a remote machine on a network.

Your unzip program will detect this anyway.stevepdp wrote:Sometimes downloads appear to be successful, but problems with the server or your own bandwidth can corrupt the contents.
The cryptographic checksum is necessary only to ensure that the image has not been deliberately tampered with, say on an insecure mirror site. If you use BitTorrent the download is already checked cryptographically.
