Why and What is ECDSA
Referenced from Instruct-able workshops others What is ECDSA ECDSA stands for “Elliptic Curve Digital Signature Algorithm”, it’s used to create a digital signature of data (a file for example) in order to allow you to verify its authenticity without compromising its security. Think of it like a real signature, you can recognize someone’s signature, but you can’t forge it without others knowing. The difference however between an ECDSA signature and a real signature is that it's simply impossible to forge the ECDSA signature. You shouldn't confuse ECDSA with AES (Advanced Encryption Standard) which is to encrypt the data. ECDSA does not encrypt or prevent someone from seeing or accessing your data, what it protects against though is making sure that the data was not tampered with. Two words are worth noting here in "ECDSA" and that's "Curve" and "Algorithm" because it means that ECDSA is basically all about mathematics. Understanding the Basic...
