Ethereum: Comment-to in the API

Ethereum: Understand the comments at API

When they interact with Ethereum Blockchain on the application programming interface (API), developers often need to send messages and receive messages between the parties. The two most commonly used methods for sending messages are “Sendrom” and “Senttoaddress”. However, one of the most important differences between the two approaches lies in how to encrypt the message.

Send from a script: Send -from

The “Send -from” method uses scripts to authenticate users before allowing them to send transactions. When using “Sendfrom”, the script is responsible for sending a message and sending it to Ethereum to the network. One of the benefits of this approach is that it allows greater control of the encryption process.

In particular, “comment-to” (or “encrypted”) uses a complex algorithm to encrypt the message with the public key of the recipient title. This means that even if an attacker gets access to the private key of the script, they can’t decode the encrypted message without the right public key.

Send to a script: Senttoaddress

On the other hand, when using the “Senttoaddress”, the recipient is specifically requested for permission before they get access to the transaction. There is some restrictions on this approach compared to the “SEND -FROM” method. While this will continue to allow users to send messages, they must first obtain an explicit permission from the recipient.

In addition, “note-to” uses simpler algorithm than “comment-to” that requires only the sha-256 hash of the message without further encryption steps.

Comparison of “note-to” and “note-to”

Here is a summary of the most important differences between “note-to” and “note-to”:

* Encryption : `Comment-to” uses a complex algorithm to encrypt the message with the public key to the recipient address, while “comment-to only requires the sha-256 hash of the message.

* Safety : “Note-to” offers more comprehensive security features as it uses a complex encryption algorithm and the recipient gives you a particularly permission.

Conclusion

When choosing between “Send -fra” and “Senttoaddress”, developers must consider their specific requirements for encryption and control of the message. For applications that require fine-grained access control and advanced security features, the “comment-to” is likely to fit better. However, in the case of simple uses or scenarios, in which development is simpler than maximum safety, “Send -from” may be sufficient.

Regardless of the approach you choose, it is essential to remember that encryption of the message should always be based on a safe cryptographic protocol such as AES-256-GCM (Galois/Counter mode), with Sha-256, and not just simple withdrawal using functions.
