## Encoders
|
|
|
|
Most of encoded data can be decoded with these 2 ressources:

|
### A1Z26
|
|
|
|
Letters to their numerical value
|
|
|
|
```text
|
|
8 15 12 1 3 1 18 1 3 15 12 1
|
|
```
|
|
|
|
### Affine Cipher Encode
|
|
|
|
Letter to num `(ax+b)%26` \(_a_ and _b_ are the keys and _x_ is the letter\) and the result back to letter
|
|
|
|
```text
|
|
krodfdudfrod
|
|
```
|
|
|
|
### SMS Code
|
|
|
|
**Multitap** [replaces a letter](https://www.dcode.fr/word-letter-change) by repeated digits defined by the corresponding key code on a mobile [phone keypad](https://www.dcode.fr/phone-keypad-cipher) \(This mode is used when writing SMS\).
|
|
For example: 2=A, 22=B, 222=C, 3=D...
|
|
You can identify this code because you will see **several numbers repeated**.
|
|
|
|
You can decode this code in: [https://www.dcode.fr/multitap-abc-cipher](https://www.dcode.fr/multitap-abc-cipher)
|
|
|
|
### Bacon Code
|
|
|
|
Substitude each letter for 4 As or Bs \(or 1s and 0s\)
|
|
|
|
```text
|
|
00111 01101 01010 00000 00010 00000 10000 00000 00010 01101 01010 00000
|
|
AABBB ABBAB ABABA AAAAA AAABA AAAAA BAAAA AAAAA AAABA ABBAB ABABA AAAAA
|
|
```
|
|
|
|
### Runes
|
|
|
|
|
|
|
|
## Compression
|
|
|
|
**Raw Deflate** and **Raw Inflate** \(you can find both in Cyberchef\) can compress and decompress data without headers.
|
|
|
|
## Easy Crypto
|
|
|
|
### XOR - Autosolver
