encrypt(text) ⇒ <code>string</code>

Encrypts a plaintext private key using AES-256-GCM. The derived key is obtained via scrypt from the environment variable WALLET_ENCRYPTION_KEY.

Kind: global function
Returns: <code>string</code> - The encrypted payload in the format iv:authTag:ciphertext (all hex encoded).

Param	Type	Description
text	<code>string</code>	The plaintext private key to encrypt.

<a name="decrypt"></a>

decrypt(encryptedData) ⇒ <code>string</code>

Decrypts an encrypted private key payload. Expected format is iv:authTag:ciphertext produced by the encrypt function. If the payload is unencrypted (legacy format), it returns the payload as-is.

Kind: global function
Returns: <code>string</code> - The plaintext private key.

Param	Type	Description
encryptedData	<code>string</code>	The encrypted payload to decrypt.

<a name="isEncrypted"></a>

isEncrypted(data) ⇒ <code>boolean</code>

Checks if a string contains an encrypted payload matching the expected AES-256-GCM hex-encoded format.

Kind: global function
Returns: <code>boolean</code> - True if the format indicates the payload is encrypted.

Param	Type	Description
data	<code>string</code>	The string payload to check.
