# Small update: A lot of people were curious how was the private key generated, so let me explain.
# You know how RSA works, right?
# The private key usually consists of two or more prime numbers, and the public key is the product of those prime numbers.
# p - prime number 1
# q - prime number 2
# n = p * q - public modulus
# e - public exponent
# They are being used to compute a private exponent d, which in this case is used to sign the payload.
# d = e^-1 mod (p-1)(q-1)
# Did you see what exactly was done to the public modulus?
# It's a prime number! But RSA is usually used with two prime numbers, right?
# And the only reason RSA is secure is because we assume that it's very hard to find the factors of a public modulus.
# And if n is a prime number, then the only factor is n - which means - RSA essentially becomes a symmetric cipher.
# So how do we get the private key? It's simple: d = e^-1 mod (n-1)
# ~ alula

Examples:
%(prog)s --patch : Generate .patched files only
%(prog)s --patch --apply : Generate patches and apply them to current IDA installation
: on macOS attempts to also re-sign the bundle
%(prog)s --license : Generate license only
%(prog)s --oneshot : Patch IDA then generate license - equivalent to running --patch --apply then --license
%(prog)s --license --name "bnuuy": Custom name
%(prog)s --oneshot --license-type floating --end-date 2030-12-31
How to use:
1. Place this script in the directory where IDA is installed and all .dll/.so/.dylib files are located.
On Windows it's C:\\Program Files\\IDA Professional 9.x\\
On Linux it's ~/ida-pro-9.x/
On macOS it's /Applications/IDA Professional 9.x.app/Contents/MacOS/
2. You most likely just want to run the script with --oneshot option, which will do everything automatically.
3. If you want run individual steps, see the options above.
Note: This version of the keygen uses a different modulus patch than the previous version.
See the source code in case you want to use the old patch.

very good, thank you 谢谢作者 谢谢LZ，脚本好始，已经用上9.2了 谢谢楼主，成功搞定macOS 26上的9.2了 有9.3的测试通过的盆友吗
