Decrypts the ClCertA files.
- Get ClCertA (TitleID 0004001b00010002). If you get it from the CDN, remember to decrypt it with its decrypted titlekey in AES-128-CBC mode.
- Decrypt the ClCertA CFA with the tool of your choice. Decrypt9, rxTools and 3DS Multi Decryptor both work as well.
- Use ctrtool to extract the RomFS from the decrypted ClCertA CFA.
- Compile ccrypt. This requires devkitPro and devkitARM or any regular cross-compiling gcc targeting arm-none-eabi.
- Place the resulting
code.bin
at the root of your SD card. - Place
ctr-common-1-cert.bin
andctr-common-1-key.bin
from your ClCertA RomFS at the root of your SD card. - Visit
http://dukesrg.no-ip.org/3ds/cakes?code.bin
with your 3DS web browser.
The resulting files are ctr-common-1-cert.dec
and ctr-common-1-key.dec
at
the root of your SD card.
They are in DER format. For usage in browsers, you may need to convert it
to the PKCS#12 format or the PEM format.
