There is no retroactive flip; you mint the key +exportable, or you regenerate. The verified recipe below passes +`-exportable` to `csptest -keyset -newkeyset`. Skipping it is the +single most common reason `certmgr -export -pfx` fails with +`0x8009000b NTE_BAD_KEY_STATE` ("Key not valid for use in specified +state"). + +## Headless RNG prerequisite — CPSD gamma + +A fresh CSP install cannot generate keys at all without seeded +software RNG. Two issues out of the box: + +- `/var/opt/cprocsp/dsrf/db{1,2}/` are empty → CPSD RNG returns + `0x80090020` ("internal error") on `-newkeyset`. +- The fallback `BIO_TUI` RNG (level 5) is **interactive** — it + prompts "Press keys to provide random data…" and any `-silent` + invocation aborts with `0x80090022` ("context was acquired as + silent"). Piping `/dev/urandom` to stdin doesn't satisfy it. + +`entrypoint.cryptopro.sh` handles both on first start: + +1. Copies the baked test gamma from + `/opt/cprocsp/share/test_gamma/db1/kis_1` into both + `/var/opt/cprocsp/dsrf/db1/kis_1` and `…/db2/kis_1`. +2. Removes BIO_TUI from the registered RNGs so CPSD (level 3) is the + only RNG available, ensuring deterministic non-interactive + behaviour under `-silent`. + +After the first `docker compose up cryptopro`, keygen works without +manual setup. To regenerate the gamma yourself (the test gamma is for +testing only — production should mint a fresh portion per +environment): + +```bash +docker compose -f docker/dev_pkcs12/docker-compose.yml exec cryptopro \ + genkpim 27 01d2c1c8 /var/opt/cprocsp/dsrf/db1/ +``` + +`genkpim ` is the official CryptoPro CPSD +generator. `27` = number of keys derivable from this CPSD portion; +`01d2c1c8` = 8-digit hex id label; trailing path is where `kis_1` +(the gamma) lands. + +## Anti-rule — do not run `/etc/init.d/cprocsp start` + +`cpinstance`'s integrity check false-positives on +`libcapi20.so.4.0.5` under docker overlay-fs and renames it to +`corrupted.libcapi20.so.4.0.5`, breaking `csptest`. The container's +CSP libraries work fine without the init.d service; entrypoint only +needs the gamma seed (above). If you accidentally trip the rename: + +```bash +docker compose exec cryptopro sh -c ' + mv /opt/cprocsp/lib/amd64/corrupted.libcapi20.so.4.0.5 \ + /opt/cprocsp/lib/amd64/libcapi20.so.4.0.5 + ln -sf libcapi20.so.4.0.5 /opt/cprocsp/lib/amd64/libcapi20.so.4 + ldconfig +' +``` + +## Verified flow — csptest `-newkeyset` + `-makecert` + +This is the actual primary path. Earlier docs referenced +`cryptcp -creatcert -keep_exportable` — that command **does not exist +in CSP 5.0.13003**. `cryptcp -help` lists `-createcert` (CA-bound, +interactive) and `-createrqst` (PKCS#10 only); neither mints a self- +signed cert in one shot. The `csptest -keycopy` "two-step exportable" +idiom is also fictional — `csptest -keycopy` has no +`-exchangeprivate`/`-signatureprivate` flags in this build. + +### Step 1 — mint exportable container + +```bash +docker compose -f docker/dev_pkcs12/docker-compose.yml exec cryptopro \ + csptest -keyset -newkeyset \ + -container '\\.\HDIMAGE\test-' \ + -provtype 80 \ + -keytype exchange \ + -exportable \ + -password 123456 +``` + +Container path syntax: `\\.\HDIMAGE\` (literal single +backslashes after shell un-escape; double-quoted single-quoted nested +heredocs eat them, mind your shell layers). `-provtype 80` = GOST +2012-256; `81` = GOST 2012-512 (note: type 81 default name is +`Crypto-Pro GOST R 34.10-2012 KC1 Strong CSP`, with "Strong"). The +`-password 123456` here **sets** the container PIN despite the help +calling it "auth". + +### Step 2 — mint self-signed cert into the container + +```bash +docker compose -f docker/dev_pkcs12/docker-compose.yml exec cryptopro \ + csptest -keyset \ + -container '\\.\HDIMAGE\test-' \ + -provtype 80 \ + -password 123456 \ + -makecert +``` + +`-makecert` synthesises subject/issuer DN as `E=test@cryptopro.ru, +CN=` automatically — there is no `-rdn` flag in +csptest. Validity defaults to roughly 4 years. Acceptable for cross- +validation; not configurable from the CLI. + +If you need a custom subject DN, you'd have to: + +- Run `cryptcp -createrqst -rdn "CN=...,O=..."` to get a PKCS#10, +- Sign it externally (e.g. via OpenSSL with the gost engine after + some round-tripping), and +- Install the resulting cert via + `certmgr -install -file -container '\\.\HDIMAGE\'`. + +For our cross-validation flow the auto-DN is sufficient. + +### Step 3 — install cert into uMy store with key-link + +```bash +docker compose -f docker/dev_pkcs12/docker-compose.yml exec cryptopro \ + certmgr -install -container '\\.\HDIMAGE\test-' +``` + +After this, `certmgr -list` shows the cert in the default `uMy` +store with `PrivateKey Link: Yes`. + +Pull the SHA-1 thumbprint for the export step: + +```bash +docker compose -f docker/dev_pkcs12/docker-compose.yml exec cryptopro \ + certmgr -list -dn "CN=test-" \ + | awk '/SHA1 Thumbprint/ {print $NF}' +``` + +### Step 4 — export PFX + +```bash +docker compose -f docker/dev_pkcs12/docker-compose.yml exec cryptopro sh -c \ + "echo '123456' | certmgr -export -pfx \ + -container '\\\\.\\HDIMAGE\\test-' \ + -dest /workspace/data/test-.pfx \ + -pin 123456" +``` + +Critical quirks: + +- **`-pin `** is the **PFX password only**. The container PIN is + requested **interactively** — pipe `123456\n` via stdin (`echo + '123456' | …`). Both happen to be `123456` in this guide, but the + channels are independent. +- **Do not pass `-silent`** — it blocks the RNG read for the PBE salt + and aborts with `0x80090022`.
