cryptoKey.usages

• 类型：<string[]>

  ¥Type: <string[]>

标识可能使用键的操作的字符串数组。

¥An array of strings identifying the operations for which the key may be used.

可能的用法是：

¥The possible usages are:

• 'encrypt' - 密钥可用于加密数据。

  ¥'encrypt' - The key may be used to encrypt data.

• 'decrypt' - 密钥可用于解密数据。

  ¥'decrypt' - The key may be used to decrypt data.

• 'sign' - 该密钥可用于生成数字签名。

  ¥'sign' - The key may be used to generate digital signatures.

• 'verify' - 密钥可用于验证数字签名。

  ¥'verify' - The key may be used to verify digital signatures.

• 'deriveKey' - 该密钥可用于导出新密钥。

  ¥'deriveKey' - The key may be used to derive a new key.

• 'deriveBits' - 密钥可用于导出位。

  ¥'deriveBits' - The key may be used to derive bits.

• 'wrapKey' - 该密钥可用于封装另一个密钥。

  ¥'wrapKey' - The key may be used to wrap another key.

• 'unwrapKey' - 该密钥可用于解包另一个密钥。

  ¥'unwrapKey' - The key may be used to unwrap another key.

有效的密钥用法取决于密钥算法（由 cryptokey.algorithm.name 标识）。

¥Valid key usages depend on the key algorithm (identified by cryptokey.algorithm.name).
