消息摘要是一个安全的、单向的哈希函数，把任意长度的数据转化成固定长度的校验和/哈希码。

Message Digests are secure, one-way hash functions that convert arbitrary length data into fixed-length check sum / hash code.

要数字签署大型文件，首先使用这些算法用一种安全的方式压缩(计算固定长度的哈希码)文件，然后再用私钥签署。

For digitally signing large files, the files are first compressed (the fixed-length hash is calculated) in a secure manner using these algorithms, and then signed with the private key.
