The outputs are added modulo 2 After the 16th round, undo the last swap, and XOR L with K18 and R with K17 (output whitening).
Decryption is exactly the same as encryption, except that P1, P2, …, P18 are used in the reverse order.
A recent analysis by Feyrer, Mansur, and Sacerdote concluded that without new U. oil and natural gas extraction, there would have been 725,000 fewer Americans working and a 0.5 percent higher unemployment rate during the Great Recession. real GDP continued growing throughout, logging a 2.9 percent increase overall for 1986, neither significantly faster nor slower than normal.
The conclusion I draw from the seemingly conflicting evidence in the macro and micro data is that each consumer spent more than they would have if oil prices had not fallen, but that there were other macro headwinds at the same time that were offsetting some of the positive stimulus of falling oil prices.
However, the Advanced Encryption Standard (AES) now receives more attention, and Schneier recommends Twofish for modern applications.
Schneier designed Blowfish as a general-purpose algorithm, intended as an alternative to the aging DES and free of the problems and constraints associated with other algorithms.
In all, the Blowfish encryption algorithm will run 521 times to generate all the subkeys - about 4KB of data is processed.
Because the P-array is 576 bits long, and the key bytes are XORed through all these 576 bits during the initialization, many implementations support key sizes up to 576 bits.
