A combinate attack. When dictionary attack finishes, a brute force attack starts:

crackpkcs12 -b -d dictionary.txt certificate.pfx

A combinate attack. When dictionary attack finishes, a brute force attack starts. Brute force attack uses just lower and upper case letters:

crackpkcs12 -d dictionary.txt -b -caA certificate.pfx

A combinate attack. When dictionary attack finishes, a brute force attack starts. Brute force attack uses just numbers and minimun length of passwords is 5:

crackpkcs12 -d dictionary.txt -b -cn -m5 certificate.pfx
