+name:                cryptohash-sha1
+version:             0.11.100.1
+x-revision: 2
+description:
+    A practical incremental and one-pass, pure API to the
+    <https://en.wikipedia.org/wiki/SHA-1 SHA-1 hash algorithm>
+    (including <https://en.wikipedia.org/wiki/HMAC HMAC> support)
+    with performance close to the fastest implementations available in other languages.
+    .
+    The implementation is made in C with a haskell FFI wrapper that hides the C implementation.
+    .
+    NOTE: This package has been forked off @cryptohash-0.11.7@ because the @cryptohash@ package has been
+    deprecated and so this package continues to satisfy the need for a lightweight package
+    providing the SHA1 hash algorithm without any dependencies on packages other than
+    @base@ and @bytestring@.
+    .
+    Consequently, this package can be used as a drop-in replacement for @cryptohash@'s
+    "Crypto.Hash.SHA1" module, though with a clearly smaller footprint.
