+.IX Item """pkcs15-pad-disabled"" (OSSL_ASYM_CIPHER_PARAM_FIPS_RSA_PKCS15_PAD_DISABLED) <integer>"
+The default value of 1 causes an error during encryption if the RSA padding
+mode is set to "pkcs1".
+Setting this to zero will ignore the error and set the approved
+"fips\-indicator" to 0.
+This option breaks FIPS compliance if it causes the approved "fips\-indicator"
+to return 0.
