Final answer:
The validity of encryption methods used in HackerRank for Goldman Sachs coding tests is not publicly disclosed and is based on specific security requirements.
Step-by-step explanation:
The question pertains to the validity period of encryption methods used in the context of HackerRank for Goldman Sachs coding tests. Since this is a specific question about the company's test security protocols, the validity of encryption is not publicly disclosed for security reasons. Generally, encryption validity would be set based on industry best practices and the specific security requirements of the company.
In the context of widely used encryption standards, validity periods can vary. For example, certificates used in TLS (Transport Layer Security) often have a set expiry of one to two years, but this is not directly related to the validity of encryption methods used in coding platforms like HackerRank. It would be best to refer directly to Goldman Sachs or HackerRank's official resources or support for the most accurate and up-to-date information on such specifics.
Industry-standard encryption validity can vary, with TLS certificates often expiring after one to two years.
