Package simonspeck implements the Simon and Speck families of NSA block ciphers. It is a straightforward translation of the pseudocode in the paper 1 into golang. THIS IMPLEMENTATION IS NOT CRYPTOGRAPHICALLY SECURE. This code correctly encodes the supplied test vectors in 1 with the following conventions: words are stored with a little-endian representation, and the test vectors are reversed (i.e., the plaintext "6565 6877" for Simon32/64 is stored as []byte{0x77, 0x68, 0x65, 0x65}. I chose this convention since with it, the Simon test vector plaintexts concatenate to the phrase "wheeling and circling round like the pillar of dust that travellers describe when there is a simoom in t" and the Speck test vector plaintexts concatenate to "Literally this means Fat-cutter; usage, however, in time made it equivalent to Chief Harpooner. In those". Each cipher implements the cipher.Block interface (godoc crypto/cipher).
