This endpoint exports a wallet’s private key using Hybrid Public Key Encryption (HPKE). The following HPKE configuration is supported:
  • KEM (Key Encapsulation Mechanism): DHKEM_P256_HKDF_SHA256
  • KDF (Key Derivation Function): HKDF_SHA256
  • AEAD (Authenticated Encryption with Associated Data): CHACHA20_POLY1305
  • Mode: BASE

​
Headers

​
privy-app-id
string
required
ID of your Privy app.
​
privy-authorization-signature
string
Request authorization signature. If multiple signatures are required, they should be comma separated.

​
Path Parameters

​
wallet_id
string
required
ID of the wallet to export.

​
Body

​
encryption_type
string
required
Currently only supports HPKE (Hybrid Public Key Encryption).
​
recipient_public_key
string
required
Base64-encoded public key of the recipient who will decrypt the private key. This key must be generated securely and kept confidential. The public key sent should be in base64-encoded DER format.

​
Response

​
encryption_type
string
required
Will be HPKE to indicate Hybrid Public Key Encryption was used.
​
ciphertext
string
required
Base64-encoded encrypted private key. The private key format depends on the wallet type: base58 for Solana wallets, hex for EVM wallets.
​
encapsulated_key
string
required
Base64-encoded ephemeral public key used in the HPKE encryption process. Required for decryption.
