STR.GENERATE RANDOM
String Commands
Intention
GENERATE RANDOM STRING - Mode: This Mode will generate a random String of specified length and from specified characters. You can use it to generate passwords.
The sequence lenght is about 2^32 for this PRNG.
For true cryptpgraphical random numbers and "One Time Pads" use other options, for example the CHAR D - Option.
The Command itself looks like this:
STR.GENERATE|$$SRC|$$CNT|$$CHR
And here is a small example:
: $$TXT=ABC
: $$NUM=5
STR.GENERATE|$$SRC|$$NUM|$$TXT
MBX.$$SRC
STR.GENERATE|$$SRC
MBX.$$SRC
ENR.
Which will bring up a Message-Box like this ..
Pic.1 Result from:
STR.GENERATE|$$SRC|$$NUM|$$TXT
and a Message-Box like this:
Pic.2 Result from:
STR.GENERATE|$$SRC
Syntax
STR.GENERATE|P1[|P2][|P3]
Parameter Explanation
P1 - source and destination variable
P2 - (optional) length of desired random string in bytes. If omitted, a default length of 32 byte length is used.
P3 - (optional) variable with all characters that should be used for the random string generation.
Alternatively you can use some small letters to define the character-Set for P3.
- empty/if P3 is omitted, then the whole charset from 255 ASC-Characters will be used.
"a" - all ASC-Character (0-255)
"b" - "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_-?#+*"
"c" - "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_-?"
"d" - "abcdefghijklmnopqrstuvwxyzöüäßABCDEFGHIJKLMNOPQRSTUVWXYZÄÜÖ"
"e" - "abcdefghijklmnopqrstuvwxyz"
"f" - "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
"g" - "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZüöäÜÖÄß'[]{}@|<>.1234567890_\-;:*+#§%&/()=! "
"h" - "0123456789ABCDEF"
"i" - "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZüöäÜÖÄß'´`[]{}@.1234567890_-;+#§%&()=! "
"k" - ":\abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZüöäÜÖÄß'[]{}@.1234567890_-;+#§%&()=! "
"m" - "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ.1234567890_\ "
"o" - "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ-"
"n" - "0123456789"
"p" - "\/:*?<>|"+ASC(34) (Double-Quotes)
"x" - "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZüöäÜÖÄß[]{}@<>.1234567890_\-;:*+#§%&/()=!"
