Member Typedef Documentation

EncryptionKeyInitializeFunction

typedef void(* EncryptionKeyInitializeFunction) (void)

Function pointer used to initialize dependencies in order to provide decryption.

This function currently cannot fail. In order to indicate failure on initialization return error code in the decrypt function itself.

Friends And Related Function Documentation

EncryptionKeyCleanupFunction

typedef void(* EncryptionKeyCleanupFunction) (void)

related

Cleanup all dependencies after the decryption process has finished.

This function is called when the last reference to the EncryptionKeyHandle has been disposed.

EncryptionKeyDecryptFunction

typedef error_type(* EncryptionKeyDecryptFunction) (const BufferHandle *data, BufferHandle **result)

related

User provided function used for decrypting data.

This function is only called when EncryptionKeyContainsFunction sets the result to true.

Parameters

data	a pointer to source buffer containing the PKCS#7 encrypted data
result	an output pointer which has to be set with the decrypted data on success. Otherwise leave unchanged.

EncryptionKeyContainsFunction

typedef error_type(* EncryptionKeyContainsFunction) (const BufferHandle *issuer, const BufferHandle *serial, boolean_type *result)

related

Function used to determine whether the private key for certificate issued by issuer with serial is present.

Parameters

issuer	a pointer to X509 NAME structure containning the certificate issuer
issuer	a pointer to ASN.1 structure containning the certificate serial
result	a pointer to boolean. Set to true, if the private key for issuer and serial is present. Otherwise set to false.

EncryptionKey_Release()

error_type EncryptionKey_Release ( EncryptionKeyHandle *  handle )

related

Decrement the internal reference counter.

When the internal counter reaches zero the object is deleted. Releasing already disposed object causes undefined behavior.
