Base64: what it is and how to convert text in Utilo

Base64 is an encoding format that transforms any binary data (such as files) into a sequence of text characters. It is widely used in APIs, emails, JSON, URLs, and various contexts where it's not possible to send binary data directly.

Despite the "weird" name, the concept is simple: instead of sending raw bytes, you send a textual version of them.

Is Base64 encryption?

No. This is a common confusion. Base64 is not a form of encryption, just a way to encode data as text. Anyone who has the Base64 content can decode it.
