RC4 加密解密单元delphi版附件压缩包里有两个单元文件，其中Rc4_Kol_Unit.pas是在delphi KOL编程时引用。若只是delphi编程只须引用Rc4_Unit.pas单元即可。函函数名: Rc4_StrEncrypt()描 述: RC4 Based string encryption参 数: i_Encrypt ——为 1 是加密, 0 是解密（integer类型）； s_En

-RC4 encryption decryption unit annex to the delphi version compression bag has two modules files, where Rc4_Kol_Unit.pas is a reference to the in delphi KOL programming. Only delphi programming only reference Rc4_Unit.pas unit can be. Letter function name: Rc4_StrEncrypt () describe: RC4 Based string encryption parameters: i_Encrypt- for an encryption, decryption (integer type)　s_En
