The mathematics certainly can be, but the fundamental concepts that developers and solution architects need every day are surprisingly approachable. The real difficulty is often understanding which tool solves which problem. Base64 is not encryption. URL encoding is not encryption either. Hashing is not reversible. Encryption provides confidentiality but not necessarily authenticity. Digital signatures do not encrypt your data. And asymmetric encryption is normally not how we encrypt large amounts of data. ...
