Use decrypt-cc20p1305 to perform decryption of a CIPHERTEXT using the CHACHA20-POLY1305 Authenticated Encryption with Associated Data (AEAD) construction described in IETF RFC 7539.

To perform decryption of a CIPHERTEXT using CHACHA20-POLY1305, use the following syntax:

(decrypt-cc20p1305 CIPHERTEXT NONCE AAD MAC PUBLIC-KEY SECRET-KEY)

Use the following arguments to specify the inputs for the decrypt-cc20p1305 Pact function:

The decrypt-cc20p1305 function returns the decrypted plaintext as an unpadded base64URL string.

The following example demonstrates the decrypt-cc20p1305 function:

In this example, decrypt-cc20p1305 is used to decrypt the ciphertext "aGVsbG8gd29ybGQh" using CHACHA20-POLY1305 with the specified nonce, additional authentication data (AAD), authentication tag (MAC), public key, and secret key. The function returns the decrypted plaintext as an unpadded base64URL string.

Use hyperlane-decode-token-message to decode a base-64-unpadded encoded Hyperlane Token Message into an object containing recipient, amount, and chainId information.

To decode a Hyperlane Token Message using hyperlane-decode-token-message, use the following syntax:

The hyperlane-decode-token-message function returns an object with the following fields:

Here's an example of using hyperlane-decode-token-message to decode a Hyperlane Token Message:

In this example, the function decodes the provided base-64-unpadded string and returns an object containing the decoded information:

Use hyperlane-encode-token-message to encode an object into a Hyperlane Token message as an unpadded base64url string.

To encode an object into a Hyperlane Token message using hyperlane-encode-token-message, use the following syntax:

The object should have the following structure:

The hyperlane-encode-token-message function returns a string representing the encoded Hyperlane Token message in unpadded base64url format.

Here's an example of using hyperlane-encode-token-message to encode an object into a Hyperlane Token message:

In this example, the function encodes the provided object into a Hyperlane Token message. The object contains:

The function returns the encoded message as an unpadded base64url string.

Use hyperlane-message-id to get the Message Id of a Hyperlane Message object.

To get the Message Id of a Hyperlane Message object using hyperlane-message-id, use the following syntax:

The Hyperlane Message object should have the following structure:

The hyperlane-message-id function returns a string representing the Message Id of the given Hyperlane Message object.

Here's an example of using hyperlane-message-id to get the Message Id of a Hyperlane Message object:

In this example, the function takes a Hyperlane Message object with the following properties:

The function returns the Message Id "9lxextceVw0b18kUdfwSze-3Iw7OE-Z5Kq9I8HTDKGE" for this Hyperlane Message object.

Use validate-keypair to verify that the Curve25519 public key and secret key you specify are base-16 strings of 32 characters match each other.

To validate a Curve25519 public and secret key pair, use the following syntax:

Use the following arguments to specify the public key and the secret key that you want to validate using the validate-keypair Pact function.

The validate-keypair function returns a boolean value indicating whether the provided key pair matches.

The following example demonstrates how to use the validate-keypair function to verify that the Curve25519 key pair composed of the public key public-key and the secret key secret-key match:
