    A federal court rules that the Atanasoff-Berry Computer (ABC) built by physicist John Atanasoff was the first electronic digital computer, invalidating what would have been immensely lucrative patents filed on the ENIAC. The ABC, which preceded the ENIAC by years, introduced the concepts of binary arithmetic, logic circuits, and regenerative memory, all of which were used in the ENIAC.

    After 210 days of work, the “Bovine RC5 Effort" cracks a RSA Data Security RC5 56-bit encryption key, the strongest encryption allowed to be exported by U.S. law at the time, as part of an organized challenge conducted by RSA in an attempt to encourage the government to approve the export of 128-bit keys. The cracked message read, “It was time to move to a longer key length." The prize for being the first of over four thousand teams to crack the key was ten thousand dollars. That challenge was the fourth to be offered by the company in 1997. The first challenge was a 40-bit key that was cracked in three hours for a thousand dollar award. The second challenge was a 48-bit key that was cracked in thirteen days for a five thousand dollar prize. The third challenge was the first of four 56-bit keys the challenge would offer. The keys were cracked using brute force methods that, in the case of this fourth challenge, required the Bovine team to attempt over forty-seven percent of the 72,057,594,037,927,936 possible keys.
