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.binat the root of your SD card.
ctr-common-1-key.binfrom your ClCertA RomFS at the root of your SD card.
http://dukesrg.no-ip.org/3ds/cakes?code.binwith your 3DS web browser.
The resulting files are
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.
