NAME

step crypto hash digest – generate a hash digest of a file or directory

USAGE

step crypto hash digest file-or-directory… [–alg=algorithm]

DESCRIPTION

step crypto hash digest generates a hash digest for a given file or directory. For a file, the output is the same as tools like ‘shasum’. For directories, the tool computes a hash tree and outputs a single hash digest.

For examples, see step help crypto hash.

POSITIONAL ARGUMENTS

file-or-directory
The path to a file or directory to hash.

OPTIONS

–alg=algorithm
The hash algorithm to use.

algorithm must be one of:

sha1 (or sha) : SHA-1 produces a 160-bit hash value

sha224 : SHA-224 produces a 224-bit hash value

sha256 (default) : SHA-256 produces a 256-bit hash value

sha384 : SHA-384 produces a 384-bit hash value

sha512 : SHA-512 produces a 512-bit hash value

sha512-224 : SHA-512/224 uses SHA-512 and truncates the output to 224 bits

sha512-256 : SHA-512/256 uses SHA-512 and truncates the output to 256 bits

md5 (requires –insecure) : MD5 produces a 128-bit hash value
