The filesha1 function computes the SHA1 hash of the contents of

a given file and encodes it as hex.

# `filesha1` Function
|
|
|
|
`filesha1` is a variant of [`sha1`](../../language/functions/sha1.mdx)
|
|
that hashes the contents of a given file rather than a literal string.
|
|
|
|
This is similar to `sha1(file(filename))`, but
|
|
because [`file`](../../language/functions/file.mdx) accepts only UTF-8 text it cannot be used to
|
|
create hashes for binary files.
|
|
|
|
Collision attacks have been successfully performed against this hashing
|
|
function. Before using this function for anything security-sensitive, review
|
|
relevant literature to understand the security implications.
