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

privy-authorization-signature
Request authorization signature. If multiple signatures are required, they should be comma
separated.
Path Parameters
ID of the wallet to export.
Body
Currently only supports HPKE (Hybrid Public Key Encryption).
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
Will be HPKE to indicate Hybrid Public Key Encryption was used.
Base64-encoded encrypted private key. The private key format depends on the wallet type: base58
for Solana wallets, hex for EVM wallets.
Base64-encoded ephemeral public key used in the HPKE encryption process. Required for decryption.
