kcapi_aead_init - initialization of cipher handle

int kcapi_aead_init(struct kcapi_handle ** handle, const char * ciphername, uint32_t flags);

handle

[out] cipher handle filled during the call

ciphername

[in] kernel crypto API cipher name as specified in /proc/crypto

flags

[in] flags specifying the type of cipher handle

This function initializes an AEAD cipher handle and establishes the connection to the kernel.

On success, a pointer to kcapi_handle object is returned in *handle. Function kcapi_aead_destroy should be called afterwards to free resources.

return 0 upon success; -ENOENT - algorithm not available; -EOPNOTSUPP - AF_ALG family not available; -EINVAL - accept syscall failed -ENOMEM - cipher handle cannot be allocated
