PKCS V1.5 Encryption Scheme Functions

This subsection describes functions implementing the RSA encryption scheme defined in version 1.5 of the PKCS#1 standard ([PKCS 1.2.1]).

The full list of these functions is given in Table “Intel IPP PKCS V1.5 Encryption Scheme Functions”.

Intel IPP PKCS V1.5 Encryption Scheme Functions
Function Base Name	Operation
RSAEncrypt_PKCSv15	Carries out the encryption using the v1.5 version of the PKCS#1 standard.
RSADecrypt_PKCSv15	Carries out the decryption using the v1.5 version of the PKCS#1 standard.

To invoke a function that carries out a PKCS V1.5 encryption scheme, the IppsRSAState context must be initialized (by the RSAInit function) with a proper value of the flag parameter:

For PKCS V1.5 encryption, flag == IppRSApublic
For PKCS V1.5 decryption, flag == IppRSAprivate.
