GALANTHUS / ABI FUNCTION REFERENCE

gln_reset_ebics_bank_keys

Declared in <galanthus/c_api/gln_capi.h>.

GLN_API gln_status_t GLN_CALL gln_reset_ebics_bank_keys(
    gln_backend_t*         in_backend,
    gln_backend_result_t** out_result);
  • Family: Backend operations
  • Return type: gln_status_t

Purpose

gln_reset_ebics_bank_keys clears trusted and pending EBICS bank-key material and returns the resulting key status.

When To Use

Use this only for a legitimate bank-key rotation, participant reset recovery, or correcting a local trust-store error.

Call Contract

GLN_OK from the function means an envelope was produced in *out_result; it does not mean the backend operation succeeded. Inspect the envelope with gln_get_backend_result_outcome, gln_get_backend_result_status, and gln_get_backend_result_kind.

out_result == NULL is the no-envelope invalid-argument case. In that case the function returns GLN_ERR_INVALID_ARG directly.

The parameter table is binding for required handles and output slots.

Return

Returns GLN_OK when the call produced a gln_backend_result_t envelope in out_result. Operation success, caller action, provider rejection, and operation errors are reported inside that envelope.

Success Result

Successful operation envelopes have outcome GLN_BACKEND_OUTCOME_SUCCESS, status GLN_OK, and kind GLN_BACKEND_RESULT_KIND_EBICS_KEY_STATUS.

Borrow the typed success view with gln_get_backend_result_ebics_key_status.

Use gln_get_backend_result_ebics_key_status only when the envelope outcome is GLN_BACKEND_OUTCOME_SUCCESS and the kind is GLN_BACKEND_RESULT_KIND_EBICS_KEY_STATUS.

The typed key-status result reports whether client keys remain and confirms that trusted and pending bank keys are absent.

Outcomes

  • GLN_BACKEND_OUTCOME_SUCCESS: read the GLN_BACKEND_RESULT_KIND_EBICS_KEY_STATUS typed view.
  • GLN_BACKEND_OUTCOME_ERROR: inspect gln_get_backend_result_status and gln_get_backend_result_error. Non-EBICS backends use this outcome with status GLN_ERR_NOT_SUPPORTED.

Bank-key reset is a local key-store operation.

Ownership And Lifetime

The envelope returned through out_result is caller-owned and must be released with gln_destroy_backend_result.

Typed views, result rows or fields, borrowed strings, and the JSON string are borrowed from the envelope. They become invalid when the envelope is destroyed. Copy strings or row data before destroying the envelope when the caller needs to keep them.

After this reset, operational EBICS calls cannot verify bank responses or encrypt uploads until HPB has staged fresh bank keys and gln_verify_pending_ebics_bank_keys has promoted them. Never use this as an automatic fallback for verification failures.
