Description of problem: When the `openssl cms` command is used to encrypt data, the command aborts when the recipient key is ECDSA Version-Release number of selected component (if applicable): openssl-3.0.1-20.el9_0.x86_64 openssl-3.0.7-20.el9.x86_64 How reproducible: always Steps to Reproduce: openssl ecparam -out p256.pem -name P-256 openssl req -x509 -newkey ec:p256.pem -keyout root.key -out root.crt -subj /CN=localhost -batch -nodes -days 36500 -sha256 echo something to encrypt > message.txt openssl cms -encrypt -in message.txt -out message.enc root.crt Actual results: (for 3.0.7-20.el9) 409C3F54CC7F0000:error:17000074:CMS routines:cms_EnvelopedData_Encryption_init_bio:error setting recipientinfo:crypto/cms/cms_env.c:1159: 409C3F54CC7F0000:error:17000068:CMS routines:CMS_final:cms lib:crypto/cms/cms_smime.c:882: Expected results: CMS file encrypted with ECDSA/ECDH Additional info: The command does succeed in FIPS mode (and produces a file encrypted with `:dhSinglePass-stdDH-sha1kdf-scheme`) and works if the KDF is explicitly set to SHA-256: openssl cms -encrypt -in message.txt -out message.enc -recip root.crt -keyopt ecdh_kdf_md:sha256 The operation also works in RHEL-8
