Functions ¶
func DirFiles ¶
DirFiles returns the list of files in the tree rooted at dir, replacing the directory name dir with prefix in each name. The resulting names always use forward slashes.
func Hash1 ¶
Hash1 is the "h1:" directory hash function, using SHA-256.
Hash1 is "h1:" followed by the base64-encoded SHA-256 hash of a summary prepared as if by the Unix command:
sha256sum $(find . -type f | sort) | sha256sum
More precisely, the hashed summary contains a single line for each file in the list, ordered by sort.Strings applied to the file names, where each line consists of the hexadecimal SHA-256 hash of the file content, two spaces (U+0020), the file name, and a newline (U+000A).
File names with newlines (U+000A) are disallowed.
func HashDir ¶
HashDir returns the hash of the local file system directory dir, replacing the directory name itself with prefix in the file names used in the hash function.
