public interface VaultTranscriber
A facade to the configured vault provider that exposes utility methods for obtaining the vault secrets in different

Method Details
-
getRawSecret
Obtains the raw secret from the vault that matches the entry in the specified value string. The value must follow the format${vault.<KEY>}
where<KEY>
identifies the entry in the vault. If the value doesn't follow the vault expression format, it is assumed to be the secret itself and is encoded into aVaultRawSecret
. The returnedVaultRawSecret
extendsAutoCloseable
and it is strongly recommended that it is used in try-with-resources blocks to ensure the raw secret is overridden (destroyed) when the calling code is finished using it.- Parameters:
value
- aString
that might be a vault expression containing a vault entry key.- Returns:
- a
VaultRawSecret
representing the secret that was read from the vault. If the specified value is not a vault expression then the returned secret is the value itself encoded as aVaultRawSecret
.
-
getCharSecret
Obtains the secret represented as aVaultCharSecret
from the vault that matches the entry in the specified value string. The value must follow the format${vault.<KEY>}
where<KEY>
identifies the entry in the vault. If the value doesn't follow the vault expression format, it is assumed to be the secret itself and is encoded into aVaultCharSecret
. The returnedVaultCharSecret
extendsAutoCloseable
and it is strongly recommended that it is used in try-with-resources blocks to ensure the raw secret is overridden (destroyed) when the calling code is finished using it.- Parameters:
value
- aString
that might be a vault expression containing a vault entry key.- Returns:
- a
VaultRawSecret
representing the secret that was read from the vault. If the specified value is not a vault expression then the returned secret is the value itself encoded as aVaultRawSecret
.
-
getStringSecret
Obtains the secret represented as aString
from the vault that matches the entry in the specified value. The value must follow the format${vault.<KEY>}
where<KEY>
identifies the entry in the vault. If the value doesn't follow the vault expression format, it is assumed to be the secret itself. Due to the immutable nature of strings and the way the JVM handles them internally, implementations that keep a reference to the secret string might consider doing so using aWeakReference
that can be cleared in theAutoCloseable.close()
method. Being immutable, such strings cannot be overridden (destroyed) by the implementation, but using aWeakReference
guarantees that at least no hard references to the secret are held by the implementation class itself (which would prevent proper GC disposal of the secrets). WARNING: It is strongly recommended that callers of this method use the returned secret in try-with-resources blocks and they should strive not to keep hard references to the enclosed secret string for any longer than necessary so that the secret becomes available for GC as soon as possible. These measures help shorten the window of time when the secret strings are readable from memory.- Parameters:
value
- aString
that might be a vault expression containing a vault entry key.- Returns:
- a
VaultStringSecret
representing the secret that was read from the vault. If the specified value is not a vault expression then the returned secret is the value itself encoded as aVaultStringSecret
.
