I've noticed that the secrets created by the ACME account setup do not specify the label "app.kubernetes.io/managed-by". This allows attributing secrets without a controller owner reference to the system response for them. This label is already used by cert-manager for the CA secret created for the API webhook.

### Release Notes
<details>
<summary>cert-manager/cert-manager (cert-manager)</summary>
### [`v1.18.1`](https://github.com/cert-manager/cert-manager/releases/tag/v1.18.1)
[Compare Source](https://github.com/cert-manager/cert-manager/compare/v1.18.0...v1.18.1)
cert-manager is the easiest way to automatically manage certificates in Kubernetes and OpenShift clusters.
We have added a new feature gate `ACMEHTTP01IngressPathTypeExact`, to allow `ingress-nginx` users to turn off the new default Ingress `PathType: Exact` behavior, in ACME HTTP01 Ingress challenge solvers.
This change fixes the following issue: [#​7791](https://github.com/cert-manager/cert-manager/issues/7791)
We have increased the ACME challenge authorization timeout to two minutes, which we hope will fix a timeout error (`error waiting for authorization`), which has been reported by multiple users, since the release of cert-manager `v1.16.0`.
This change should fix the following issues: [#​7337](https://github.com/cert-manager/cert-manager/issues/7337), [#​7444](https://github.com/cert-manager/cert-manager/issues/7444), and [#​7685](https://github.com/cert-manager/cert-manager/issues/7685).

### [`v1.17.0`](https://github.com/cert-manager/cert-manager/releases/tag/v1.17.0)
[Compare Source](https://github.com/cert-manager/cert-manager/compare/v1.16.5...v1.17.0)
cert-manager is the easiest way to automatically manage certificates in Kubernetes and OpenShift clusters.
v1.17.0 is a feature release with several improvements, including:
- A helpful compliance change to RSA signatures on certificates
- An easier way to specify passwords for [PKCS#12](https://github.com/PKCS/cert-manager/issues/12) and JKS keystores
- A few feature flag promotions (and a deprecation)
- Dependency bumps and other smaller improvements
#### Major Themes
##### RSA Certificate Compliance
The United States Department of Defense published [a memo](https://dl.dod.cyber.mil/wp-content/uploads/pki-pke/pdf/unclass-memo_dodcryptoalgorithms.pdf) in 2022 which introduced some requirements on the kinds of cryptography they require to be supported in software they use.
In effect, the memo requires that software be able to support larger RSA keys (3072-bit and 4096-bit) and hashing algorithms (SHA-384 at a minimum).
cert-manager supported large RSA keys long before the memo was published, but a quirk in implementation meant that cert-manager always used SHA-256 when signing with RSA.
In v1.17.0, cert-manager will choose a hash algorithm based on the RSA key length: 3072-bit keys will use SHA-384, and 4096-bit keys will use SHA-512. This matches similar behavior already present for ECDSA signatures.
Our expectation is that this change will have minimal impact beyond a slight increase to security and better compliance; we're not aware of Kubernetes based environments which support RSA 2048 with SHA-256 but fail with RSA 4096 and SHA-512. However, if you're using larger RSA keys, you should be aware of the change.
##### Easier Keystore Passwords for [PKCS#12](https://github.com/PKCS/cert-manager/issues/12) and JKS
Specifying passwords on [PKCS#12](https://github.com/PKCS/cert-manager/issues/12) and JKS keystores is supported in cert-manager
for compatibility reasons with software which expects or requires passwords to be set; however, these passwords are [not relevant to security](https://cert-manager.io/docs/faq/#why-are-passwords-on-jks-or-pkcs12-files-not-helpful) and never have been in cert-manager.
The initial implementation of the `keystores` feature required these "passwords" to be stored in a Kubernetes secret, which would then be read by cert-manager when creating the keystore after a certificate was issued. This is cumbersome, especially when many passwords are set to default values such as `changeit` or `password`.
In cert-manager v1.17, it's now possible to set a keystore password using a literal string value inside the `Certificate` resource itself, making this process much easier with no change to security.
For example:
```yaml
apiVersion: cert-manager.io/v1
kind: Certificate
metadata:
name: my-cert-password
spec:
secretName: my-cert-password
issuerRef:
name: my-issuer
kind: ClusterIssuer
keystores:
jks:
create: true
password: "abc123"
pkcs12:
create: true
password: "password"
dnsNames:
- example.com
```
The new `password` field is mutually exclusive with the `passwordSecretRef` field, so be sure to only set one.
##### Feature Flag Promotions / Deprecations
cert-manager's feature flags allow for easier testing and adoption of new features with a reduced risk of breaking changes. In cert-manager v1.17, two feature gates have been promoted to "beta", and as such are now enabled by default in all installations:
- `NameConstraints`, allowing users to specify the name constraints extension which can be helpful when creating CA certificates for private PKI
- `UseDomainQualifiedFinalizer`, which stops a Kubernetes warning from being printed in logs
In addition, we added a new feature gate: `CAInjectorMerging`, which intelligently combines certificates used by the [`CAInjector`](../../concepts/ca-injector.md) component, making it safer to use when issuing certificates are rotated. If you're making heavy use of the CA injector, you should consider enabling this feature gate.
Finally, we deprecated the `ValidateCAA` feature gate which will be removed entirely in cert-manager v1.18.0. This feature gate aimed to validate the `CAA` DNS record during ACME issuance, but has seen low adoption and limited testing since its introduction back in 2019.
##### Other Changes
There are many other PRs which were merged in this release cycle and we'd encourage you to read the release notes below. One PR that's worth highlighting is a change to add more structured logging information to certain log lines.
If you were previously filtering logs using `grep` or similar tools (which is highly discouraged!) be aware that some log lines have changed format.

#### Changes by Kind
##### Feature
- Potentially BREAKING: The CA and SelfSigned issuers now use SHA-512 when signing with RSA keys 4096 bits and above, and SHA-384 when signing with RSA keys 3072 bits and above. If you were previously using a larger RSA key as a CA, be sure to check that your systems support the new hash algorithms.

### [`v1.16.2`](https://github.com/cert-manager/cert-manager/releases/tag/v1.16.2)
[Compare Source](https://github.com/cert-manager/cert-manager/compare/v1.16.1...v1.16.2)
cert-manager is the easiest way to automatically manage certificates in Kubernetes and OpenShift clusters.
This patch release of cert-manager 1.16 makes [several changes](https://github.com/cert-manager/cert-manager/pull/7401) to how PEM input is validated, adding maximum sizes appropriate to the type of PEM data which is being parsed.
This is to prevent an unacceptable slow-down in parsing specially crafted PEM data. The issue was found by Google's OSS-Fuzz project.
The issue is low severity; to exploit the PEM issue would require privileged access which would likely allow Denial-of-Service through other methods.
Note also that since most PEM data parsed by cert-manager comes from `ConfigMap` or `Secret` resources which have a max size limit of approximately 1MB, it's difficult to force cert-manager to parse large amounts of PEM data.
Further information is available in https://github.com/cert-manager/cert-manager/security/advisories/GHSA-r4pg-vg54-wxx4
In addition, the version of Go used to build cert-manager 1.16 was updated along with the base images.
#### Changes by Kind
##### Bug or Regression
- Set a maximum size for PEM inputs which cert-manager will accept to remove possibility of taking a long time to process an input ([#​7401](https://github.com/cert-manager/cert-manager/issues/7401), [@​SgtCoDFish](https://github.com/SgtCoDFish))
##### Other (Cleanup or Flake)
- Bump go to 1.23.3 and bump base images to latest available ([#​7431](https://github.com/cert-manager/cert-manager/issues/7431), [@​SgtCoDFish](https://github.com/SgtCoDFish))

#### 📜Changes since `v1.16.0`
##### Bug or Regression
- BUGFIX: Helm schema validation: the new schema validation was too strict for the "global" section. Since the global section is shared across all charts and sub-charts, we must also allow unknown fields. ([#​7348](https://github.com/cert-manager/cert-manager/pull/7348), [`@inteon`](https://github.com/inteon))

### [`v1.15.4`](https://github.com/cert-manager/cert-manager/releases/tag/v1.15.4)
[Compare Source](https://github.com/cert-manager/cert-manager/compare/v1.15.3...v1.15.4)
cert-manager is the easiest way to automatically manage certificates in Kubernetes and OpenShift clusters.
This patch release of cert-manager 1.15 makes [several changes](https://github.com/cert-manager/cert-manager/pull/7403) to how PEM input is validated, adding maximum sizes appropriate to the type of PEM data which is being parsed.
This is to prevent an unacceptable slow-down in parsing specially crafted PEM data. The issue was found by Google's OSS-Fuzz project.
The issue is low severity; to exploit the PEM issue would require privileged access which would likely allow Denial-of-Service through other methods.
Note also that since most PEM data parsed by cert-manager comes from `ConfigMap` or `Secret` resources which have a max size limit of approximately 1MB, it's difficult to force cert-manager to parse large amounts of PEM data.
Further information is available in https://github.com/cert-manager/cert-manager/security/advisories/GHSA-r4pg-vg54-wxx4
In addition, the version of Go used to build cert-manager 1.15 was updated along with the base images, and a Route53 bug fix was backported.

Pull Request Motivation
I've noticed that the secrets created by the ACME account setup do not specify the label "app.kubernetes.io/managed-by". This allows attributing secrets without a controller owner reference to the system response for them.
This label is already used by cert-manager for the CA secret created for the API webhook.
