You can easily generate a public key using the <,keygen>, tag in HTML. The <,keygen>, element generates an encryption key for passing encrypted data to a server. The purpose of the <,keygen>, element is to provide a secure way to authenticate users.
How public key is generated?
The public key is made available to anyone (often by means of a digital certificate).

What is key generator HTML?
The <,keygen>, tag in HTML is used to specify a key-pair generator field in a form. The purpose of <,keygen>, element is to provide a secure way to authenticate users.

How does API key look like?
Yes, they look like hashes. After all, you don’t want them to be easy to guess. More or less – most bog standard API keys are generated by hashing some pseudorandom value and performing some standard plain-text encoding on the result, e.g. base16, base64 etc.
