Since R2026a

Syntax

removeSecretMetadata(secretname)

v = removeSecretMetadata(secretname,Keys=keynames)

Description

removeSecretMetadata(secretname) removes the entire metadata dictionary of the specified secret in your MATLAB vault.

v = removeSecretMetadata(secretname,Keys=keynames) removes just the metadata dictionary elements associated with the specified keys.

Examples

Remove Metadata from Secret

Remove all metadata from a secret.

removeSecretMetadata(secretname)

Remove Specific Metadata from Secret

getSecretMetadata(secretname)

Remove two elements from the metadata of the secret.

removeSecretMetadata(secretname,Keys=["metadatakey1","metadatakey2"])

View the updated metadata of the secret.

getSecretMetadata(secretname)

Input Arguments

secretname — Unique case-sensitive text identifier for secret

string scalar | character vector

Unique case-sensitive text identifier for the secret, specified as a string scalar or character vector.

keynames — Key names in metadata dictionary

string array | character vector | cell array of character vectors

Key names in metadata dictionary, specified as a string array, character vector, or cell array of character vectors. removeSecretMetadata removes only the dictionary elements associated with the specified keys. If a specified key does not exist, then removeSecretMetadata returns an error.

If you do not specify keynames, then removeSecretMetadata removes all metadata associated with the secret name.

More About

MATLAB Vault

Your secrets are stored in your MATLAB^® vault. Your vault and secrets persist across MATLAB sessions.

Each secret consists of a name, value, and optional metadata.

• Secret name – A unique case-sensitive text identifier for the secret. The secret name is stored unencrypted in your vault as a string scalar.

• Secret value – A text value associated with the secret. The Secret Prompt dialog box, where you enter the secret value, supports copy-paste functionality. The secret value is stored encrypted in your vault using industry standard AES-256 encryption. The secret value is returned as a string scalar.

• Secret metadata – A dictionary containing additional information associated with the secret. The optional secret metadata is stored unencrypted in your vault.

On an installed version of MATLAB, your vault is accessible only from the exact combination of your operating system account and local machine, and your vault and secrets do not leave your local machine. With MATLAB Online™, your vault is accessible with your MathWorks Account, and your vault and secrets are stored on a secure database on MathWorks^® servers. For increased security when you use MATLAB Online, enable two-step verification for your MathWorks Account.

To set an individual secret, use setSecret. The Secret Prompt dialog box, where you enter the secret value, supports copy-paste functionality. To import secrets from a file, use importSecrets.
