RSA BSAFE Crypto-C Micro Edition 3.x to 4.1.4 Migration Guide
For Crypto-C ME 4.1.4, the R_CR_RES_CRYPTO_CUSTOM_METHOD resource is
replaced by the following individual resources:
• R_CR_CRYPTO_CTX_BASE
•
R_CR_CRYPTO_ASYM_BASE
•
R_CR_CRYPTO_KXCHG_BASE
•
R_CR_CRYPTO_KGEN_BASE
•
R_CR_CRYPTO_PGEN_BASE
•
R_CR_CRYPTO_KEYWRAP_BASE
•
R_CR_CRYPTO_KDF_BASE
•
R_CR_CRYPTO_RNG_BASE
•
R_CR_CRYPTO_MAC_BASE
•
R_CR_CRYPTO_DIGEST_BASE
•
R_CR_CRYPTO_CIPHER_BASE
•
R_CR_CRYPTO_SIGNATURE_BASE
The following code examples show the conversion of a custom resources list
containing only symmetric cipher functionality and the AES 128-bit CBC symmetric
key algorithm. For other examples of custom resource lists in Crypto-C ME 4.1.4, see
the RSA BSAFE Crypto-C Micro Edition Developers Guide.
