You can build and install it from source using cargo:
console
cargo install basecracker
Current supported encodings
- base2 / binary (padding by 7, 8, 9, 10)

<h2>Example</h2>
<p><code>console
$ basecracker -e "Awsome CTF tool" -b b64,b85,hex,b32,b62,b58

Awsome CTF tool
$ basecracker -c 2SYnX25ZB1torUZ1AmsobB58ESDjzHzb2dJTZuwt22KfynQP1eRjxPoumGWiA45iGpRw2sx5LVB1D8K8xaLTTetafmPs3a44oiaFxrg3s4d4fkWJ36UzrSFWuLL6WbdQ5nbQSBCV7gC2DCzrxpaj
Recipe: base58 -> base62 -> base32 -> hex -> base85 -> base64
Result: Awsome CTF tool

<h2>JSON output</h2>
<p>BaseCracker can output results in JSON format. This is useful for other tools that can parse JSON output.</p>
<p><code>console
$ basecracker -c 2SYnX25ZB1torUZ1AmsobB58ESDjzHzb2dJTZuwt22KfynQP1eRjxPoumGWiA45iGpRw2sx5LVB1D8K8xaLTTetafmPs3a44oiaFxrg3s4d4fkWJ36UzrSFWuLL6WbdQ5nbQSBCV7gC2DCzrxpaj -j | jq
