• File src/OFSHA1Hash.m — part of check-in [d310aeee30] at 2014-08-31 17:59:31 on branch trunk — Rewrite OFSHA1Hash

  The old one was based on a public domain implementation, which is
  optimized for old compilers and quite unreadable. The new one is written
  from scratch and designed to be readable and to exploit optimizations of
  modern compilers. (user: js, size: 3537) [annotate] [blame] [check-ins using]

To Artifact [20f00e8f54]:

• File src/OFSHA1Hash.m — part of check-in [23dc2c7ff8] at 2014-09-01 10:47:15 on branch trunk — OF{MD5,SHA1}Hash: Zero _buffer when done

  This way, possibly sensitive information is discarded from memory as
  soon as possible. (user: js, size: 3576) [annotate] [blame] [check-ins using]
