RSA_public_encrypt() encrypts the B<flen> bytes at B<from> (usually a
session key) using the public key B<rsa> and stores the ciphertext in
-B<to>. B<to> must point to B<RSA_size(rsa)> bytes of memory.
+B<to>. B<to> must point to RSA_size(B<rsa>) bytes of memory.
B<padding> denotes one of the following modes:
=back
-B<flen> must be less than RSA_size(rsa) - 11 for the PKCS #1 v1.5
-based padding modes, and less than RSA_size(rsa) - 21 for
-RSA_PKCS1_OAEP_PADDING. The random number generator must be seeded
-prior to calling RSA_public_encrypt().
+B<flen> must be less than RSA_size(B<rsa>) - 11 for the PKCS #1 v1.5
+based padding modes, less than RSA_size(B<rsa>) - 41 for
+RSA_PKCS1_OAEP_PADDING and exactly RSA_size(B<rsa>) for RSA_NO_PADDING.
+The random number generator must be seeded prior to calling
+RSA_public_encrypt().
RSA_private_decrypt() decrypts the B<flen> bytes at B<from> using the
private key B<rsa> and stores the plaintext in B<to>. B<to> must point
to a memory section large enough to hold the decrypted data (which is
-smaller than B<RSA_size(rsa)>). B<padding> is the padding mode that
+smaller than RSA_size(B<rsa>)). B<padding> is the padding mode that
was used to encrypt the data.
=head1 RETURN VALUES
RSA_public_encrypt() returns the size of the encrypted data (i.e.,
-RSA_size(rsa)). RSA_private_decrypt() returns the size of the
+RSA_size(B<rsa>)). RSA_private_decrypt() returns the size of the
recovered plaintext.
On error, -1 is returned; the error codes can be
