Gunakan CreateGrant dengan AWS SDK atau CLI

Untuk membuat hibah

create-grantContoh berikut membuat hibah yang memungkinkan exampleUser pengguna untuk menggunakan decrypt perintah pada KMS kunci 1234abcd-12ab-34cd-56ef-1234567890ab contoh. Kepala sekolah yang pensiun adalah adminRole perannya. Hibah menggunakan batasan EncryptionContextSubset hibah untuk mengizinkan izin ini hanya jika konteks enkripsi dalam decrypt permintaan menyertakan pasangan nilai "Department": "IT" kunci.

aws kms create-grant \
    --key-id 1234abcd-12ab-34cd-56ef-1234567890ab \
    --grantee-principal arn:aws:iam::123456789012:user/exampleUser \
    --operations Decrypt \
    --constraints EncryptionContextSubset={Department=IT} \
    --retiring-principal arn:aws:iam::123456789012:role/adminRole

Output:

{
    "GrantId": "1a2b3c4d2f5e69f440bae30eaec9570bb1fb7358824f9ddfa1aa5a0dab1a59b2",
    "GrantToken": "<grant token here>"
}
