LiveCode Forums.

Hi:

I would like to know if the PC1 algorithm is implemented in LiveCode somewhere (My search did not found results).

Thanks.

PC1 is not currently supported in the LiveCode engine, though one could write an external if that specific algo is needed.

You can, however, use the built-in "encrypt" command for strong security using keys of 128 or 256 bits as PC1 does - see the Dictionary entry for the "encrypt" command for details.

Hola garduino,

1. welcome to the forum!

2. I entered "put the ciphernames" into the message box and this is what I got,
item 1 is the name of the algorithm, item 2 the key lengths in bits:
aes-128-cbc,128
aes-128-cfb,128
aes-128-cfb1,128
aes-128-cfb8,128

Should fit your needs somehow

Thanks you guys!

Yes, I know the built-in algo's provided by LiveCode, just asking is someone implemented the PC1, because I need to deal with an old piece of software and surely will need it.

Thanks!

Another question about this is, encrypt/decrypt is not supported in mobile platforms, as I saw. How do you guys solve this, how do you encrypt/decrypt in Android/iOS ?

Thanks.
