This subsection describes functions implementing the RSA signature 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 Signature Scheme Functions”.
| Function Base Name | Operation |
|---|---|
| RSASSASign_MD5_PKCSv15 | Generates a signature using the v1.5 version of the RSA scheme with the MD5 message digest. |
| RSASSASign_SHA1_PKCSv15 | Generates a signature using the v1.5 version of the RSA scheme with the SHA-1 message digest. |
| RSASSASign_SHA224_PKCSv15 | Generates a signature using the v1.5 version of the RSA scheme with the SHA-224 message digest. |
| RSASSASign_SHA256_PKCSv15 | Generates a signature using the v1.5 version of the RSA scheme with the SHA-256 message digest. |
| RSASSASign_SHA384_PKCSv15 | Generates a signature using the v1.5 version of the RSA scheme with the SHA-384 message digest. |
| RSASSASign_SHA512_PKCSv15 | Generates a signature using the v1.5 version of the RSA scheme with the SHA-512 message digest. |
| RSASSAVerify_MD5_PKCSv15 | Verifies a signature using the v1.5 version of the RSA scheme with the MD5 message digest. |
| RSASSAVerify_SHA1_PKCSv15 | Verifies a signature using the v1.5 version of the RSA scheme with the SHA-1 message digest. |
| RSASSAVerify_SHA224_PKCSv15 | Verifies a signature using the v1.5 version of the RSA scheme with the SHA-224 message digest. |
| RSASSAVerify_SHA256_PKCSv15 | Verifies a signature using the v1.5 version of the RSA scheme with the SHA-256 message digest. |
| RSASSAVerify_SHA384_PKCSv15 | Verifies a signature using the v1.5 version of the RSA scheme with the SHA-384 message digest. |
| RSASSAVerify_SHA512_PKCSv15 | Verifies a signature using the v1.5 version of the RSA scheme with the SHA-512 message digest. |
To invoke a function that carries out a PKCS V1.5 signature scheme, the IppsRSAState context must be initialized (by the RSAInit function) with a proper value of the flag parameter:
