+.Sh DESCRIPTION
+These functions provide the RC4 stream cipher in the
+.Xr evp 3
+framework.
+It is a variable key length cipher.
+.Pp
+.Fn EVP_rc4
+uses a default key length of 128 bits.
+.Pp
+.Fn EVP_rc4_40
+uses a key length of 40 bits instead.
+This function is deprecated.
+Use
+.Fn EVP_rc4
+and
+.Xr EVP_CIPHER_CTX_set_key_length 3
+instead.
+.Pp
+.Fn EVP_rc4_hmac_md5
+provides authenticated encryption with the RC4 stream cipher
+with MD5 as HMAC.
+This function is not intended for usage outside of TLS
+and requires calling of some undocumented control functions.
+It does not conform to the EVP AEAD interface.
+.Sh RETURN VALUES
+These functions return an
+.Vt EVP_CIPHER
+structure that provides the implementation of the symmetric cipher.
