System and method for interapplication communications

A computer system, comprising:

• a processing system comprising one or more processors;
• and
• a memory comprising one or more tangible computer-readable media,
• wherein the memory includes instructions that, when executed by the processing system, cause the processing system to perform operations comprising:
• determining a validity of a digital certificate associated with a first executable program;
• obtaining a portion of a license agreement associated with a second executable program;
• when the digital certificate is valid, generating an instruction to provide a challenge to the first executable program, the challenge instructing the first executable program to encrypt the obtained portion of the license agreement provided by the second executable program;
• receiving a response to the challenge from the first executable program, the response comprising the encrypted portion of the license agreement and a digital signature applied to the encrypted portion of the license agreement;
• decrypting the received response using a public key associated with the digital certificate to generate a decrypted portion of the license agreement;
• and
• determining whether the obtained portion of the license agreement corresponds to the decrypted portion of the license agreement;
• and
• when the decrypted portion of the license agreement corresponds to the obtained portion of the license agreement, enabling communications with the first executable program in a manner consistent with the license agreement, and enabling the first executable program to access one or more functions of the second executable program in accordance with the license agreement.

A tangible, non-transitory computer-readable medium storing instructions that, when executed by at least one processor, cause the at least one processor to perform a method, comprising:

• determining a validity of a digital certificate associated with a first executable program;
• obtaining a portion of a license agreement associated with a second executable program;
• when the digital certificate is valid, generating an instruction to provide a challenge to the first executable program, the challenge instructing the first executable program to encrypt the obtained portion of the license agreement provided by the second executable program;
• receiving a response to the challenge from the first executable program, the response comprising the encrypted portion of the license agreement and a digital signature applied to the encrypted portion of the license agreement;
• decrypting the received response using a public key associated with the digital certificate to generate a decrypted portion of the license agreement;
• and
• determining whether the obtained portion of the license agreement corresponds to the decrypted portion of the license agreement;
• and
• when the obtained portion of the license agreement corresponds to the decrypted portion of the license agreement, enabling communications with the first executable program in a manner consistent with the license agreement, and enabling the first executable program to access one or more functions of the second executable program in accordance with the license agreement.
