Akelarre is the Basque term meaning Witches' Sabbath. It is also found in Spanish with the spelling aquelarre. It is the place where witches hold their meetings.
Akerra means male goat in the Basque language. This term was used by witch hunters as a synonym for witches' sabbats, which they envisioned as presided over by a goat. The word is most famous as the title of the witchcraft painting by Goya, which depicts witches in the company of a huge male goat. The equivalent word in Castilian is Aqeularre.
Akelarre is a block cipher proposed in 1996, combining the basic design of IDEA with ideas from RC5. It was shown to be susceptible to a ciphertext-only attack in 1997.
Akelarre is a 128-bit block cipher with a variable key-length which must be some multiple of 64 bits. The number of rounds is variable, but four are suggested. The round function of Akelarre is similar to IDEA in structure.
After the successful cryptanalysis of Akelarre, its designers responded with an updated variant called Ake98. This cipher differs from the original Akelarre in the new AR-box (Addition-Rotation box), the swapping of words at the end of a round, and the addition of subkeys at the beginning of each round. In 2004, Jorge Nakahara, Jr. and Daniel Santana de Freitas found large classes of weak keys for Ake98. These weak keys allow a cryptanalysis faster than exhaustive search using only 71 known plaintexts, for up to 11.5 rounds of Ake98.
Akelarre is a 1984 Spanish period drama film directed by Pedro Olea. Akelarre means " Witches' Sabbath" in English, and the film is about witchcraft trials directed against the Araitz witches. It was entered into the 34th Berlin International Film Festival.
Akelarre is the seventh studio album by the thrash metal band Criminal.
