sha1-string

Arguments: string &key start end external-format return

Using sha1-init (which creates a context), sha1-update (which updates the context with the argument string), and sha1-final (which finalizes the hash), this function computes the SHA1 hash for string.

The start and end arguments specify the portion of the string to be considered and the external-format argument specifies the external hashing of the string that will be used to update the context. start defaults to 0, end defaults to the length of string, and external-format defaults to the default external format. These arguments, along with string, are passed to sha1-update.

The format of the result, just as for sha1-final, is determined by the return keyword argument. The possible values are :integer, :usb8, and :hex. See sha1-final for information on these values and the corresponding formats of the returned value.

cl-user(4): (sha1-string "foo")  ;; default return format :integer
