Crypt> function

[hagchr]

I have had a look at the Crypt> function and also some of the related old forum posts.

Is my understanding correct that the encyption strength (32, 64, or 96 bit) refers to the max length of the key? For example if you set CRYPT_LEVEL=1 then the active pass key cannot be greater than 32 bit, ie 4 characters (4*8=32). I tried an example that seems to confirm it - any characters after the first 4 have no impact.

Some of the old forum posts are using longer pass keys without changing the CRYPT_LEVEL which would then be less secure than the writer thinks.

Code: Select all

Let>CRYPT_LEVEL=1
//CRYPT_LEVEL=1 32 bit
//CRYPT_LEVEL=2 64 bit
//CRYPT_LEVEL=3 96 bit

Let>str=This is a test of the Crypt function.

Let>key1=abcd321
Crypt>key1,str,res1
mdl>res1

Let>key2=abcd123
Crypt>key2,res1,res2
MDL>res2
