others have commented, but it's really pretty varied. - literally yesterday used it for building a payload for a vuln that used a java deserialization vulnerability against a known private key for AES encryption. I built the serialized payload using ysoserial as per normal, but then b64 encoded that, then encrypted with the known key and urlencoded the final output.. then I can simply hand that off to curl or burp or whatever. - sometimes it's as simple as other said, encode/decode chains of various formats -- it's just faster especially if I'm not sure how it was encoded, but I recognize particular patterns (e.g.: url encode, b64 super easy to recognize visually, so plug and play of recipes makes it fast to try stuff out and tune).
