I want to calculate a cryptographic checksum using 3DES in outer CBC mode. As I know (and tried Googling also ) 3DES is an encryption algorithm, I'm not getting getting any information about how it ...
I'm trying to audit kerberos passwords. The available formats are des3-hmac-sha1 and des-cbc-crc but I cannot find a possibility/a tool to crack them. For other hash-types I used John the Ripper, but ...
If i have two 56-bit DES keys, and I use these two key to encrypt a 256-bit AES key. Like this: K_AT encrypts K_BT and K_BT encrypts K What is the effective security of key K? Is it 2 X 56 Bits?
I have an un-ciphered OTA message in clear and I am trying to cipher it so it becomes secure data. The cryptographic checksum is already generated as part of the un-ciphered OTA message. I have the ...
I want to implement a triple DES CBC algorithm but I do not know whether or not I should use a different IV for every encryption-decryption or the same. I suspect the same IV should be used in all 3 ...
