digest - 计算消息摘要
/usr/bin/digest -l | [-v] -a algorithm [-t truncation] [file]...
digest 实用程序使用指定算法计算给定文件或 stdin 的消息摘要。如果指定多个文件,则输出的每一行都是一个文件的摘要。
支持以下选项:
指定加密或解密过程中要使用的算法的名称。有关详细信息,请参见“用法”部分的“算法”。
显示系统上可用的算法的列表。此列表可依加密框架的配置而变化。
Verbose output.在输出中包括算法名称和文件名。This produces output similar to the GNU coreutils digest utilities, md5sum(1), sha1sum(1), sha256sum(1), sha512sum(1), etc.
指定摘要截断长度,其中 t 表示任何小于 512 的正数。仅对 sha512_t 算法有效。
The supported algorithms are displayed by the –l option.这些算法由加密框架提供。这些值与 –a 选项一起使用,并且区分大小写。
The following example generates the SHA256 digest of the file /etc/motd:
example$ digest -a sha256 /etc/motd e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855
The following example displays the SHA512/256 digest of the file /etc/motd:
example $ digest -a sha512_t -t 256 /etc/motd 1917c02fbf36970f354defef8c089adf5767cec93c3ca2b28fe29958c4361e69示例 2 生成目录清单
The following example generates a directory manifest with SHA-1:
example$ digest -v -a sha1 /usr/lib/inet/* sha1 (/usr/lib/inet/certdb) = f6d43e6e395d50db24d34e4af4828598c8918b16 sha1 (/usr/lib/inet/certlocal) = 7f74ba4a019b809c7023212b4bda10d9485e071d sha1 (/usr/lib/inet/certrldb) = 1f845d30b8d02066647de04311e74549049852ed sha1 (/usr/lib/inet/dhcp) = e3db5e4ff40a69d13f2497254526c2015d2c37b3 sha1 (/usr/lib/inet/dsvclockd) = b61aad7ed6a0f82145c3c26aedc613ab4a1f032e sha1 (/usr/lib/inet/in.dhcpd) = 382210180c826fbb2e747236c489062bac8cc30b sha1 (/usr/lib/inet/in.iked) = be6061fad725d37256e773dc85f8bd5248649463 sha1 (/usr/lib/inet/in.mpathd) = 5bd6bf0340fd5c4cc0c53f2df158302a0e85f9d0 sha1 (/usr/lib/inet/in.ndpd) = fdb768aebe7e5eb4465e1c1bb5e679b496f5c5c6 sha1 (/usr/lib/inet/in.ripngd) = 4f56a0df2d4a252f581a73c2e84143b920d0b66b sha1 (/usr/lib/inet/wanboot) = a8b8c51c389c774d0be2ae43cb85d1b1439484ae sha1 (/usr/lib/inet/ntpd) = 5b4aff102372cea801e7d08acde9655fec81f07c示例 3 显示可用算法的列表
以下示例显示可用于生成摘要的算法的列表:
example $ digest -l sha1 md5 sha224 sha256 sha384 sha512 sha512_t sha3_224 sha3_256 sha3_384 sha3_512
将返回以下退出值:
成功完成。
出现错误。
