Proposed fix: [ODBC Driver 18 for SQL Server / sqlcmd / bcp] 'SSL Provider: ... certificate verify failed: unable to get local issuer certificate' after upgrading from Driver 17 — Encrypt now defaults
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Production: install the server's CA/cert on the client and connect with a name in the cert (or HostNameInCertificate / ServerCertificate 18.1+). Dev/local only: Encrypt=no/optional or TrustServerCertificate=yes; sqlcmd -No / bcp -Yo for optional encryption.
Option: Trust the certificate or relax encryption for dev [evidence: official_recommended_action]
Applies when: See record scope.
Steps:
1. Prod: add the CA to the OS trust store; connect with the cert's DNS name
2. Dev: ...;Encrypt=yes;TrustServerCertificate=yes; or Encrypt=optional
3. sqlcmd: add -No for optional encryption
Expected: Command proceeds without the error.
Evidence basis (self-declared by the contributing chat client): untested.
