+Message Digests
+====================
+
+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:: cryptography.primitives.hashes.SHA1()
+
+    SHA-1 is a cryptographic hash function standardized by NIST. It has a
+    160-bit message digest.
+
+    .. method:: update(string)
+
+        :param bytes string: The bytes you wish to hash.
+
+    .. method:: digest()
+
+        :return bytes: The message digest as bytes.
+
+    .. method:: hexdigest()
+
+        :return str: The message digest as hex.
+
+
+SHA-2 Family
+~~~~~~~
+
+.. class:: cryptography.primitives.hashes.SHA224()
+
+    SHA-224 is a cryptographic hash function from the SHA-2 family and
+    standardized by NIST. It has a 224-bit message digest.
+
+    .. method:: update(string)
+
+        :param bytes string: The bytes you wish to hash.
+
+    .. method:: digest()
+
+        :return bytes: The message digest as bytes.
+
+    .. method:: hexdigest()
+
+        :return str: The message digest as hex.
+
+.. class:: cryptography.primitives.hashes.SHA256()
+
+    SHA-256 is a cryptographic hash function from the SHA-2 family and
+    standardized by NIST. It has a 256-bit message digest.
+
+    .. method:: update(string)
+
+        :param bytes string: The bytes you wish to hash.
+
+    .. method:: digest()
+
+        :return bytes: The message digest as bytes.
+
+    .. method:: hexdigest()
+
+        :return str: The message digest as hex.
+
+.. class:: cryptography.primitives.hashes.SHA384()
+
+    SHA-384 is a cryptographic hash function from the SHA-2 family and
+    standardized by NIST. It has a 384-bit message digest.
+
+    .. method:: update(string)
+
+        :param bytes string: The bytes you wish to hash.
+
+    .. method:: digest()
+
+        :return bytes: The message digest as bytes.
+
+    .. method:: hexdigest()
+
+        :return str: The message digest as hex.
+
+.. class:: cryptography.primitives.hashes.SHA512()
+
+    SHA-512 is a cryptographic hash function from the SHA-2 family and
+    standardized by NIST. It has a 512-bit message digest.
+
+    .. method:: update(string)
+
+        :param bytes string: The bytes you wish to hash.
+
+    .. method:: digest()
+
+        :return bytes: The message digest as bytes.
+
+    .. method:: hexdigest()
+
+        :return str: The message digest as hex.
+
+RIPEMD160
+~~~~~~~
+
+.. class:: cryptography.primitives.hashes.RIPEMD160()
+
+    RIPEMD160 is a cryptographic hash function that is part of ISO/IEC
+    10118-3:2004. It has a 160-bit message digest.
+
+    .. method:: update(string)
+
+        :param bytes string: The bytes you wish to hash.

+        :param bytes string: The bytes you wish to hash.
+
+    .. method:: digest()
+
+        :return bytes: The message digest as bytes.
+
+    .. method:: hexdigest()
+
+        :return str: The message digest as hex.
+
+MD5
+~~~~~~~
+
+.. warning::
+
+    MD5 is a deprecated hash algorithm that has practical known collision
+    attacks. You are strongly discouraged from using it.
+
+.. class:: cryptography.primitives.hashes.MD5()
+
+    MD5 is a deprecated cryptographic hash function. It has a 160-bit message
+    digest and has practical known collision attacks.
