Abstract

Disclosed are various embodiments for confirming transactions between cryptographic applications. A transaction confirmation is generated using metadata for ciphertext data. The transaction confirmation is signed using a private key of a temporary key pair. The signed transaction confirmation and a public key of the temporary key pair are converted into a publication format. The signed transaction confirmation and the public key of the temporary key pair are then published in the publication format.

Claims

1. A method, comprising:

generating, via a computing device, a transaction confirmation using metadata for ciphertext data;

signing, via the computing device, the transaction confirmation using a private key of a temporary key pair;

converting, via the computing device, the signed transaction confirmation and a public key of the temporary key pair into a publication format; and

publishing, via the computing device, the signed transaction confirmation and the public key of the temporary key pair in the publication format.

2. The method of claim 1, further comprising:

determining, via the computing device, whether the publication format comprises an electronic mail (E-mail) message; and

signing, via the computing device, the E-mail message using a daily certificate in response to determining that the publication format comprises the E-mail message.

3. The method of claim 1, wherein the signed transaction confirmation and the public key of the temporary key pair are published separately.

4. The method of claim 1, further comprising generating, via the computing device, the temporary key pair.

5. The method of claim 1, wherein the temporary key pair is generated daily.

6. The method of claim 1, wherein the publication format comprises a bar code.

7. The method of claim 1, wherein the transaction confirmation comprises information associated a corresponding transaction, the information comprising a first identifier corresponding to an originator of the transaction confirmation, a second identifier corresponding to a recipient of the transaction confirmation, and a cryptographic hash of data exchanged in the corresponding transaction, and a time at which the corresponding transaction occurred.

8. A system, comprising:

a computing device; and

an application executable in the computing device, the application comprising;

logic that generates a transaction confirmation using metadata for ciphertext data;

logic that signs the transaction confirmation using a private key of a temporary key pair;

logic that converts the signed transaction confirmation and a public key of the temporary key pair into a publication format; and

logic that publishes the signed transaction confirmation and the public key of the temporary key pair in the publication format.

9. The system of claim 8, wherein the application further comprises:

logic that determines whether the publication format comprises an electronic mail (E-mail) message; and

logic that signs the E-mail message using a daily certificate in response to determining that the publication format comprises the E-mail message.

10. The system of claim 8, wherein the signed transaction confirmation and the public key of the temporary key pair are published separately.

11. The system of claim 8, wherein the application further comprises logic that generates the temporary key pair.

12. The system of claim 8, wherein the temporary key pair is generated daily.

13. The system of claim 8, wherein the publication format comprises a bar code.

14. The system of claim 8, wherein the transaction confirmation comprises information associated a corresponding transaction, the information comprising a first identifier corresponding to an originator of the transaction confirmation, a second identifier corresponding to a recipient of the transaction confirmation, and a cryptographic hash of data exchanged in the corresponding transaction, and a time at which the corresponding transaction occurred.

15. A non-transitory computer readable medium comprising a program executable by a computing device, the program comprising:

code that generates a transaction confirmation using metadata for ciphertext data;

code that signs the transaction confirmation using a private key of a temporary key pair;

code that converts the signed transaction confirmation and a public key of the temporary key pair into a publication format; and

code that publishes the signed transaction confirmation and the public key of the temporary key pair in the publication format.

16. The non-transitory computer readable medium of claim 15, wherein the program further comprises:

code that determines whether the publication format comprises an electronic mail (E-mail) message; and

code that signs the E-mail message using a daily certificate in response to determining that the publication format comprises the E-mail message.

17. The non-transitory computer readable medium of claim 15, wherein the signed transaction confirmation and the public key of the temporary key pair are published separately.

18. The non-transitory computer readable medium of claim 15, wherein the program further comprises code that generates the temporary key pair.

19. The non-transitory computer readable medium of claim 15, wherein the temporary key pair is generated daily.

20. The non-transitory computer readable medium of claim 15, wherein the publication format comprises a bar code.
