I use a block cipher algorithm for encryption that requires the clear data bytes to be in blocks of 8 bytes, so I pad the last incomplete block with some characters.

我对需要将明文数据字节放在8字节块的加密使用块密码算法，所以我用一些字符填充最后一个不完整的块。

RC2 is a block cipher algorithm.

RC 2是一个块密码算法。

The algorithm is referred to as a stream or block cipher depending on whether the algorithm transforms the message one byte at a time or a block (eight bytes) at a time.

算法被称作流密码(stream cipher)还是块密码(block cipher)，取决于算法转换消息时是一次一个字节还是一次一个块(8个字节)。
