Delphi:采用BASE64算法流加密，编码多个字节，可以编码奇数字节和基数字节，把编码好的块写到流中，当然也可进行BASE64算法流的解密，解密的数据输入到流中，还可进行BASE64算法字符串加密，字符串解密等，比较全的BASE64加密与解密实例，仅供参考。

-Delphi: a stream cipher algorithm using BASE64 encoding a plurality of bytes, and the base may be encoded odd byte byte written to the encoded stream in a good block, of course, also be BASE64 algorithm to decrypt the stream, the decrypted data stream is input to the , and also for BASE64 string encryption algorithm, decryption string, compare the BASE64 encryption and decryption examples for reference only.
