10 Best Free Online HMAC Generator Websites

Here is a list of best free online HMAC generator websites. HMAC or Hash Based Message Authentication Code is a code to authenticate messages. It uses cryptographic hash functions like SHA256, SHA512, etc., along with a secret key or cryptographic key. The advantage of HMAC over other authentication codes is that it is much more secure as it uses hashing as well as MAC. To generate HMAC code, users need these HMAC generator websites.

Using these websites, users can quickly generate HMAC codes using desired cryptographic hash functions like SHA256, SHA512, RC2, MD4, and more. Besides the cryptographic hash function, users also need to provide text that they want to authenticate along with a secret key. Some of these websites can also encode the output HMAC code using base64 and hex code. The process to generate HMAC code is not that difficult. To help out novice users, I have included the steps of HMAC code generation in the description of each website.

These websites also come with a good set of code beautifier tools that may come in handy. Some of the code beautifier tools that they offer are CSS Minifier, JSS Minifier, XML Validator, HTML Validator, JAVA Beautifier, and more. Go through the list to know more about these websites.
