The PKA_Encrypt verb encrypts (wraps) input data using an RSA public key. The
data that you encrypt may include:
For keys, the encrypted data can be formatted according to RSA DSI PKCS #1
block type 2 format specifications. See “PKCS #1 Formats” on page D-19.
Other data, such as a digital signature, can be RSA-ciphered using the public
key and the ZERO-PAD option. The data that you provide will be padded on
the left with zero bits to the modulus length of the public key. When validating
a digital signature using the ZERO-PAD option, you are responsible for
formatting of the hash and any other required information.
Restrictions
The RSA public-key modulus size (key size) is limited by the Function Control
Vector to accommodate governmental export and import regulations.
A message can be encrypted provided that it is smaller than the public key
modulus.
The ZERO-PAD rule-array keyword is only available starting with Release 2.50.

rule_array_count
The rule_array_count parameter is a pointer to an integer variable containing
the number of elements in the rule_array variable. The value must be one for
this verb.
