.SH "NAME"
kcapi_akcipher_init \- initialize cipher handle

.SH "ARGUMENTS"
.PP
\fIhandle\fR
.RS 4
[out] cipher handle filled during the call
.RE
.PP
\fIciphername\fR
.RS 4
[in] kernel crypto API cipher name as specified in /proc/crypto

.SH "DESCRIPTION"
.PP
This function provides the initialization of an asymmetric cipher handle and establishes the connection to the kernel\&.
.PP
On success, a pointer to kcapi_handle object is returned in *handle\&. Function kcapi_akcipher_destroy should be called afterwards to free resources\&.
.PP
\fIreturn\fR
0 upon success; \-ENOENT \- algorithm not available; \-EOPNOTSUPP \- AF_ALG family not available; \-EINVAL \- accept syscall failed \-ENOMEM \- cipher handle cannot be allocated
