How hashing works for beginners:
Following on from the discussion of public/private key encryption in the first video in this series, here we introduce hashing and hash functions. This second video explains the concepts behind hashing and how it can be used with public/private key encryption to digitally sign documents. These are key elements of a trustless system. Using these techniques we can rely on cryptographic proof, rather than trusted intermediaries.
This video: • How secure is 256 bit security? gives an excellent overview of how secure the SHA256 hashing algorithm is. SHA256 (along with RIPEMD160) are two of the hashing algorithms used on the Bitcoin blockchain
