-A 160-bit nonce
+A 160-bit nonce
.I N
is chosen at random. Let
-.IR K \ =\ N \ ||\ K .
+.IR K \ =\ N \ ||\ K .
Generate 320 bits of output from RIPEMD-160 in
MGF1 mode with seed
.IR K ;
giving the ciphertext
.IR y\*(us0\*(ue .
Let \*(*t be the 160-bit tag obtained from RIPEMD-160 in HMAC mode on
-the message
-.I y\*(us0\*(ue
+the message
+.I y\*(us0\*(ue
and with key
.IR K\*(usT\*(ue .
The ciphertext is then
