@@ -3,16 +3,6 @@ Mbed TLS sample programs
 
 This subdirectory mostly contains sample programs that illustrate specific features of the library, as well as a few test and support programs.
 
-### Generic public-key cryptography (`pk`) examples
-
-* [`pkey/gen_key.c`](pkey/gen_key.c): generates a key for any of the supported public-key algorithms (RSA or ECC) and writes it to a file that can be used by the other pk sample programs.
-
-* [`pkey/pk_sign.c`](pkey/pk_sign.c), [`pkey/pk_verify.c`](pkey/pk_verify.c): loads a PEM or DER private/public key file and uses the key to sign/verify a short string.
-
-### ECDSA and RSA signature examples
-
-* [`pkey/rsa_sign_pss.c`](pkey/rsa_sign_pss.c), [`pkey/rsa_verify_pss.c`](pkey/rsa_verify_pss.c): loads an RSA private/public key and uses it to sign/verify a short string with the RSASSA-PSS algorithm.
-
 ### SSL/TLS sample applications
 
 * [`ssl/dtls_client.c`](ssl/dtls_client.c): a simple DTLS client program, which sends one datagram to the server and reads one datagram in response.
