Binary Cipher Encoder / Decoder

Plain text to encode

Cipher text to decode

Expanded bits

Byte groups (8 bits each)

Decoded text

Rules:
- Digits 0/1 = literal bits.
- A=10, a=01.
- Uppercase B–G = runs of 1s, lowercase b–g = runs of 0s.
- Pair compression:
H= Bb, h= bB
I= Cc, i= cC
J= Dd, j= dD
K= Ee, k= eE
L= Ff, l= fF
M= Gg, m= gG
- Extra compression:
Z= AA, z= aa
