PsaAsymmetricDecrypt
Decrypt a short message with a private key. Opcode: 11 (0x000B)
Parameters
| Name | Type | Description |
|---|---|---|
key_name | String | Name of the key to use for the operation |
alg | AsymmetricEncryption | An asymmetric encryption algorithm that is compatible with the type of key |
ciphertext | Vector of bytes | Short message to decrypt |
salt | Vector of bytes | Salt to use during encryption, if supported by the algorithm |
key_namemust be the name of an RSA asymmetric key pair. The key must allow the usage flagdecrypt.saltcan be provided if supported by the algorithm. If the algorithm does not support salt, pass an empty vector. If the algorithm supports optional salt, pass an empty vector to indicate no salt. For RSA PKCS#1 v1.5 encryption, no salt is supported.
Results
| Name | Type | Description |
|---|---|---|
plaintext | Vector of bytes | Buffer containing the decrypted message |
Specific response status codes
PsaErrorNotPermitted: The key does not have thedecryptflag, or it does not permit the requested algorithm.
Description
This function will decrypt a short message with the private key of the provided key pair.
