数据加密和程序通用软件系统,可广泛地用于各种微型计算机和主机。Psypher接受输入文件(二进制的和/或ASCⅡ-EBCDIC),并把这些文件或经过二进制处理,把这些文件变化为完全不可懂的随机比特序列、或者通过字符处理,产生随机字符序列。编码二进制文件的记录长度是随机的、字符文件是固定的,要编码的文件并不变更。分配的每个副本都有其自己的独特算法,所以不会出现两个Psypher副本相同的情况。该系统要求大约8千个16位字进行运算,运算时间机器与机器之间是各不相同的。现在已有装配组件形式的Psypher、它可在通用数据、(Data General)数字(Cigital)IBM和CDC硬件上工作。价格范围:用于微型计算机的为八百美元,用
Data Encryption and Programware Common software system for a wide range of microcomputers and mainframes. Psypher accepts input files (binary and / or ASCII-EBCDIC) and either transforms these files into binary, transforms them into completely unreadable random bit sequences or generates character sequences by character manipulation. The length of the record encoding binary file is random, the character file is fixed, the file to be encoded does not change. Each copy assigned has its own unique algorithm, so the same situation does not appear for both copies of Psypher. The system requires about 8,000 16-bit words to operate on, computing time machines and machines are different. There is now Psypher, an assembly component that works on Universal Data, Digital General IBM and CDC hardware. Price range: 800 dollars for microcomputers, used
