+===============
+
+.. currentmodule:: cryptography.hazmat.primitives.hashes
+
+.. class:: BaseHash(data=None)
+
+   Abstract base class that implements a common interface for all hash
+   algorithms that follow here.
+
+   If ``data`` is provided ``update(data)`` is called upon construction.
+
+    .. method:: update(data)
+
+        :param bytes data: The bytes you wish to hash.
+
+    .. method:: copy()
+
+        :return: a new instance of this object with a copied internal state.
+
+    .. method:: digest()
+
+        :return bytes: The message digest as bytes.
+
+    .. method:: hexdigest()
+
+        :return str: The message digest as hex.
+
+SHA-1
+~~~~~
+
+.. attention::
+
+    NIST has deprecated SHA-1 in favor of the SHA-2 variants. New applications
+    are strongly suggested to use SHA-2 over SHA-1.
+
+.. class:: SHA1()
+
+    SHA-1 is a cryptographic hash function standardized by NIST. It has a
+    160-bit message digest.
+
+SHA-2 Family
+~~~~~~~~~~~~
+
+.. class:: SHA224()
+
+    SHA-224 is a cryptographic hash function from the SHA-2 family and
+    standardized by NIST. It has a 224-bit message digest.
+
+.. class:: SHA256()
+
+    SHA-256 is a cryptographic hash function from the SHA-2 family and
+    standardized by NIST. It has a 256-bit message digest.
+
+.. class:: SHA384()
+
+    SHA-384 is a cryptographic hash function from the SHA-2 family and
+    standardized by NIST. It has a 384-bit message digest.
+
+.. class:: SHA512()
+
+    SHA-512 is a cryptographic hash function from the SHA-2 family and
+    standardized by NIST. It has a 512-bit message digest.
+
+RIPEMD160
+~~~~~~~~~
+
+.. class:: RIPEMD160()
+
+    RIPEMD160 is a cryptographic hash function that is part of ISO/IEC
+    10118-3:2004. It has a 160-bit message digest.
+
+Whirlpool
+~~~~~~~~~
+
+.. class:: Whirlpool()
+
+    Whirlpool is a cryptographic hash function that is part of ISO/IEC
+    10118-3:2004. It has a 512-bit message digest.
+
+MD5
+~~~
+
+.. warning::
+
+    MD5 is a deprecated hash algorithm that has practical known collision
+    attacks. You are strongly discouraged from using it.
+
+.. class:: MD5()
+
+    MD5 is a deprecated cryptographic hash function. It has a 128-bit message
+    digest and has practical known collision attacks.
