There are a few disadvantages of Triple DES including processing times in which the more complex the longer it takes. Another disadvantage is when the file or hard drive crash, it's hard to recover.

At what retailers can Acer computer accessories be purchased?
Many online and retail stores sell accessories for Acer computers. You can often find high-quality accessories from mass-merchandisers such as Walmart and Target but they are likely to have a limited selection. Your best choice for a wide selection at good prices would be online merchants such as Amazon and Newegg.

Comapre between double DES and Triple DES?
double DES is less secure than triple DES triple DES is much slower than double DES double DES is within the range of brute force attack. but triple DES is not in the range of brute force attack.
Is there Triple DES c program source code?
There's a project that's implemented Triple DES in C over at SourceForge called "Easy Triple DES." It's in alpha, but should at the very least give you a head start. (See link.)
What is triple encryption?
For some time it has been common practice to protect and tansport a key for DES encryption with triple-DES (3DES). The function follows an encrypt-decrypt-encrypt (EDE) sequence. Decrypt sequence is simply the same (encrypt) operation with the keys reversed.
What are the encryption algorithms used in ATM?
fot the past 25 years single des algorithm was used. But now triple des is used in atm cards for the encryption and decryption.

What are the drawbacks of des algorithm?
The Data Encryption Standard (DES) is a block cipher that uses a symmetric key (shared secret) algorithm. DES is now considered to be insecure for many applications. This is chiefly due to the 56-bit key size being too small; in January, 1999, a group of computer experts collaborated to publicly break a DES key in 22 hours and 15 minutes. There are also some analytical results which demonstrate theoretical weaknesses in the cipher, although they are infeasible to mount in practice. The algorithm is believed to be practically secure in the form of "Triple DES". Triple DES uses a "key bundle" which comprises three DES keys, K1, K2 and K3, each of 56 bits (excluding parity bits).The encryption algorithm is: ciphertext = EK3(DK2(EK1(plaintext)))in other words, DES encrypt with K1, DES decrypt with K2, then DES encrypt with K3.Decryption is the reverse: plaintext = DK1(EK2(DK3(ciphertext)))in other words, decrypt with K3, encrypt with K2, then decrypt with K1.Each triple encryption encrypts one block of 64 bits of data. The strongest application of Triple DES is to use 3 independent keys so that you get 3 x 56 = 168 independent key bits, but it is not uncommon to simplify the operation by just using two keys, making K1 and K3 the same but making sure K2 is independent of K1. This second Keying option provides less security than using 3 independent keys, with 2 x 56 = 112 key bits. This second option is stronger than simply DES encrypting twice, e.g. with K1 and K2, because it protects against meet-in-the-middle attacks.In recent years, the DES cipher has been superseded by the Advanced Encryption Standard (AES). Furthermore, DES has been withdrawn as a standard by NIST (previously known as NBS).
Where can someone go to find information on Triple A car insurance?
Triple A car insurance is offered by the Automobile Association of America, and information can be found on the AAA website. Additional information on AAA car insurance, including advantages and disadvantages, can be found on the CarsDirect website.
What performs three rounds of encryption using three different 56-bit keys giving an effective key length of 168 bits?
It sounds like you are describing Triple DES.The Triple-DES variant of DES (Data Encryption Standard) was developed after it became clear that DES by itself was too easy to crack. It uses three 56-bit DES keys, giving a total key length of 168 bits. Encryption using Triple-DES is simplyencryption using DES with the first 56-bit keydecryption using DES with the second 56-bit keyencryption using DES with the third 56-bit keyIn practice, Triple DES is sometimes executed using just two keys, with the 1st key being reused in step 3, i.e. 3rd key = 1st key.Decryption is done in the reverse of encryption.decryption using DES with the third 56-bit keyencryption using DES with the second 56-bit keydecryption using DES with the first 56-bit keyA couple notes here:The effective security of TripleDES is equivalent to 112-bit key (two 56-bit keys), rather than a 168-bit key. The algorithm has certain redundancies which weaken the overall strength, so use of three keys yields only the one more key's worth of strength, not the expected 3-keys.The common usage of reusing the 1st key as the 3rd key is proven to weaken TripleDES significantly to modern attacks. In fact, it reduces the strength of the algorithm back down to no stronger than ordinary 1-key DES. DON'T DO IT.Also, be careful when you say "rounds". This is different that you think. DES itself has multiple rounds of work in its implementation. That is, for DES, you don't just take the key and the plaintext, and perform some one operation on it. Rather, multiple rounds of operations are done, each using the preceding's output as its input. I mention this, because the term "round" has a specific meaning in the world of cryptography, which is different than the layman's usage.
