I removed the "type IDs" here, because these are *packet type* IDs. The only IDs we're using in the text are *signature types*. I believe signature type IDs are the only IDs that application developers sometimes think about in numerical terms.

An inline-signed OpenPGP message consists of three segments:
1. **One-pass signature packets**: These one or more packets precede the signed data and enable signature computation in one pass. See[One-Pass Signature Packet (Type ID 4)](https://www.ietf.org/archive/id/draft-ietf-openpgp-crypto-refresh-12.html#one-pass-sig) of the RFC.
1. [**One-pass signature packets**](https://www.ietf.org/archive/id/draft-ietf-openpgp-crypto-refresh-12.html#one-pass-sig): These one or more packets precede the signed data and enable signature computation in one pass.
2. **Literal data**: This is the original data (e.g., the body of a message) that the user wishes to encrypt or sign, without additional interpretation or conversion. [Literal Data Packet (Type ID 11)](https://www.ietf.org/archive/id/draft-ietf-openpgp-crypto-refresh-12.html#lit).
2. [**Literal data packet**](https://www.ietf.org/archive/id/draft-ietf-openpgp-crypto-refresh-12.html#lit): This contains the original data (e.g., the body of a message), without additional interpretation or conversion.
3. **Data signature packets**: These contain the cryptographic signature corresponding to the original data.
#### Creation
To produce an inline signature, the signer processes the entirety of the data by reading from an input file and writing into am output OpenPGP message file. As the data is processed, the signer simultaneously calculates a cryptographic signature. This procedure results in a data signature packet being appended to the output OpenPGP message file, an essential step for efficient signing.
