     Triple DES (Data Encryption Standard), sometimes refered to as 3DES, is a
-    block cipher standardized by NIST. Triple DES should be considered to be
-    cryptographically broken and should not be used for new applications, old
-    applications should strongly consider moving away from it.
+    block cipher standardized by NIST. Triple DES has known cryptoanalytic
+    flaws, however none of them currently enable a practical attack.
+    Nonetheless, Triples DES is not reccomended for new applications because it
+    is incredibly slow, old applications should consider moving away from it.
