83 * \brief Import a transparent key into a PKCS#11 token
84 *
85 * This function imports a PK object containing a
86 * public key or a private-public key pair into a
87 * PKCS#11 token.
88 *
89 * \param ctx PK context, which must contain a transparent pk
90 * object (type \c MBEDTLS_PK_RSA,
91 * \c MBEDTLS_PK_RSASSA_PSS, \c MBEDTLS_PK_ECKEY or
92 * \c MBEDTLS_PK_ECDSA).
93 * \param flags Mask of \c MBEDTLS_PKCS11_FLAG_XXX and
94 * \c MBEDTLS_PK_FLAG_XXX, applying as follows:
95 * - \c MBEDTLS_PKCS11_FLAG_TOKEN: PKCS#11 \c CKA_TOKEN
96 * flag: if set, import as token object; if clear,
97 * import as session object.
98 * - \c MBEDTLS_PK_FLAG_EXTRACTABLE: PKCS#11
99 * \c CKA_EXTRACTABLE flag: if set, the key will be
100 * extractable at least in wrapped form; if clear,
101 * the key will not be extractable at all.
102 * - \c MBEDTLS_PK_FLAG_SENSITIVE: PKCS#11
103 * \c CKA_SENSITIVE flag: if set, the key will be
104 * not be extractable in plain form; if clear, the
105 * key will be extractable at least in wrapped form.
106 * - \c MBEDTLS_PK_FLAG_SIGN: if set, the private key
107 * will be authorized for signing.
108 * - \c MBEDTLS_PK_FLAG_VERIFY: if set, the public key
109 * will be authorized for verification.
110 * - \c MBEDTLS_PK_FLAG_DECRYPT: if set, the private key
111 * will be authorized for signing.
112 * - \c MBEDTLS_PK_FLAG_ENCRYPT: if set, the public key
113 * will be authorized for encryption.
114 *
115 * \param hSession Cryptoki session.
116 * \param hPublicKey If non-null, on output, Cryptoki handle of the public
117 * key. If null, the public key is not imported.
118 * \param hPrivateKey If non-null, on output, Cryptoki handle of the private
119 * key. If null, the private key is not imported.
120 *
121 * \return 0 on success,
122 * or MBEDTLS_ERR_PK_XXX error code.
123 *
124 * \note If \c hPrivateKey is non-null then \c ctx must contain
125 * a full key pair. If \c hPrivateKey is null then \c ctx
126 * may contain a full key pair or just a public key.
127 *
128 * \note On failure, the values returned in \c hPublicKey and
129 * \c hPrivateKey will normally be \c CK_HANDLE_INVALID.
130 * One of them may be a valid handle in the unlikely case
131 * where the creation of one key object succeeded but
132 * the second one failed and destroying the first one
133 * also failed, for example because the token was
134 * disconnected.
