Whether the key may be exported.
A public key or the public part of a key pair may always be exported regardless of the value of this permission flag.
If a key does not have export permission, implementations shall not allow the key to be exported in plain form from the cryptoprocessor, whether through psa_export_key() or through a proprietary interface. The key may however be exportable in a wrapped form, i.e. in a form where it is encrypted by another key.

| #define PSA_KEY_USAGE_COPY ((psa_key_usage_t)0x00000002) |
Whether the key may be copied.
This flag allows the use of psa_copy_key() to make a copy of the key with the same policy or a more restrictive policy.
For lifetimes for which the key is located in a secure element which enforce the non-exportability of keys, copying a key outside the secure element also requires the usage flag PSA_KEY_USAGE_EXPORT. Copying the key inside the secure element is permitted with just PSA_KEY_USAGE_COPY if the secure element supports it. For keys with the lifetime PSA_KEY_LIFETIME_VOLATILE or PSA_KEY_LIFETIME_PERSISTENT, the usage flag PSA_KEY_USAGE_COPY is sufficient to permit the copy.

| #define PSA_KEY_USAGE_ENCRYPT ((psa_key_usage_t)0x00000100) |
Whether the key may be used to encrypt a message.
This flag allows the key to be used for a symmetric encryption operation, for an AEAD encryption-and-authentication operation, or for an asymmetric encryption operation, if otherwise permitted by the key's type and policy.
For a key pair, this concerns the public key.

| #define PSA_KEY_USAGE_DECRYPT ((psa_key_usage_t)0x00000200) |
Whether the key may be used to decrypt a message.
This flag allows the key to be used for a symmetric decryption operation, for an AEAD decryption-and-verification operation, or for an asymmetric decryption operation, if otherwise permitted by the key's type and policy.
For a key pair, this concerns the private key.
Definition at line 1816 of file crypto_values.h.
| #define PSA_KEY_USAGE_SIGN_HASH ((psa_key_usage_t)0x00001000) |
Whether the key may be used to sign a message.
This flag allows the key to be used for a MAC calculation operation or for an asymmetric signature operation, if otherwise permitted by the key's type and policy.
For a key pair, this concerns the private key.
Definition at line 1826 of file crypto_values.h.
| #define PSA_KEY_USAGE_VERIFY_HASH ((psa_key_usage_t)0x00002000) |
Whether the key may be used to verify a message signature.
This flag allows the key to be used for a MAC verification operation or for an asymmetric signature verification operation, if otherwise permitted by by the key's type and policy.
For a key pair, this concerns the public key.
