Hello

i try to brutforce AES 128 ECB i got

Integer overflow detected in keyspace of mask: ?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1


AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA:BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB

A is crypted length and for B is decryped length

i want to brutforce for search key used for decrypt A to B

and i use this commande

hashcat.exe -m 26401 AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA:BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB -o cracked.txt -a 3 -1 C:\Users\xxxx\Desktop\hashcat-6.2.5\charsets\DES_full.hcchr --hex-charset ?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1 -w 4 --force --opencl-device-types 1 -w 4

can help for this

You could search for integer overflow in the forum and you will find that keyspace is stored as an unsigned 64-bit integer.
If your keyspace is larger than 2^64-1 then you get the error. Looks like you're using 16 ?1. charset^16 < 2^64-1, thus your charset has to be less than 16 letters to not get an error. Still that will probably take centuries to complete.

Thanks for reply

can you help for good command for start my brutforce ??

Reduce you charset (DES_full.hcchr) to only 15 characters to fit within the character limit. The command is good.
Again like your other thread with the integer overflow it will take a very very long time!
