No. The size of the key=value block is specified on the first request
line. Please try to follow documentation that Amos has pointed you to:
https://wiki.squid-cache.org/Features/AddonHelpers#SSL_server_certificate_validator

If that documentation is missing some details, we should fix it.

Glad you found
src/security/cert_validators/fake/security_fake_certverify.pl.in. I hope
it still works!
