+Example Recipes
+===============
+
+
+## Brute force single-byte xor
+
+   for i in $(seq 255); do cat data | xor $i; done
+
+
+## Pretty xor brute force
+
+For each attempt, display the value used in the xor, and hexdump the result
+
+    for i in $(seq 255); do printf "=== %02x\n" $i; cat data | xor $i | hd; done
+
+
+## Brute force xor of base64-encoded data
+
+Same pretty-print as before, and also pipe to `less` so we can page through it.
+
+    for i in $(seq 255); do
+      printf "=== %02x\n" $i; cat data.txt | base64 -d | xor $i | hd
+    done | less
+
+ 
+## Protocol manipulation
+
+For each ICMP packet, drop the first 5 octets, and base64-decode the remainder, preserving conversation chunks
+
+    cat input.pcap | pcat | grep ICMP | while read ts proto src dst payload; do 
+      printf "%s -> %s (%s)\n" $src $dst $ts
+      echo $payload | unhex | slice 5 | base64 -d | hd
+    done
+
+
+## Elementary protocol analysis framework
+
+This merges (by time) `file1.pcap` and `file2.pcap`,
+decoding payloads from each one,
+hex dumping payloads,
+and displaying meta information about each.
+It displays information conversationally,
+sort of like wireshark's "Follow TCP Stream",
+but with more details about meta-information.
