SHA-1

In cryptography, SHA-1 (Secure Hash Algorithm 1) is a cryptographic hash function designed by the United States National Security Agency and is a U.S. Federal Information Processing Standard published by the United States NIST. SHA-1 produces a 160-bit (20-byte) hash value known as a message digest. A SHA-1 hash value is typically rendered as a hexadecimal number, 40 digits long.

SHA-1 is no longer considered secure against well-funded opponents. In 2005, cryptanalysts found attacks on SHA-1 suggesting that the algorithm might not be secure enough for ongoing use, and since 2010 many organizations have recommended its replacement by SHA-2 or SHA-3.Microsoft,Google and Mozilla have all announced that their respective browsers will stop accepting SHA-1 SSL certificates by 2017.

The SHA-1 hash function

SHA-1 produces a message digest based on principles similar to those used by Ronald L. Rivest of MIT in the design of the MD4 and MD5 message digest algorithms, but has a more conservative design.

sha. (* January 11, 1972 in Hartberg) is an Austrian artist and perception researcher. He became known through his multimedia art projects such as the House of Music in Vienna and through the artistic lounger object AlphaSphere.

Biography

In 1990, Andreas Rodler started studying Composition, Music theory and Electro acoustics at the University of Music and performing arts in Vienna and the Centre Pompidou in Paris. From 1995 to 1996 he spent several months at the sound lab IRCAM – Centre Pompidou Paris. His AlphaSphere was one of the Austrian contributions at International Contemporary Furniture Fair (ICFF 2008) in New York.

Since the middle of the nineties, his artistic work focuses on human perception. In his works, he uses symphonic orchestra, experimental music theatre, sound installations and self-made sound objects. He develops video works, interactive exhibitions and media projects Cooperation with ORF, WDR, BR, ARTE, RADIO FRANCE, EBU.

Today he uses the pseudonym „sha.“ and works on multisensory projects, which aim for new synaesthetic fields of perception through a connection of all senses. Starting with the medium “sound“, connections to other sensations (such as colour, light, shape, haptics, warmth and scent) are established.
