I'm using kotlin 19 and JVM 21.

We recently moved to maverick-synergy-client 3.1.2 (upgraded from 3.0.11 where everything worked well). This issue occurs without any additional dependencies.

Also tried using version 3.1.0 and got the same result.

When trying to create a private key to be used in maverick-synergy-client I got an error "Unable to locate a cryptographic provider"

Here's the code which I'm using to create the key:

val baseKey = """
            -----BEGIN OPENSSH PRIVATE KEY-----
            [replace_this]
            -----END OPENSSH PRIVATE KEY-----
        """.trimIndent()

        val privateKey = "mt-private-key"

        return try {
            SshKeyUtils.getPrivateKey(baseKey.replace("[replace_this]", privateKey), uhlsportProperties.passphrase)
        } catch (e: Exception) {
            null
        }
        return null
    }

Before upgrading, instead of failing, the following code was triggered in maverick-synergy-client which returned correctly:

OpenSSHPrivateKeyFile(formattedkey)

After upgrading, the function getPrivateKey is failing and returning the error "Unable to locate a cryptographic provider"

I Tried using an older key directly as a string in order to avoid the key string replacement, also started using SshClientBuilder from Maverick, but no success with creating the key for the client.

Note that I need to use string replacement because the real key is stored in a vault which cannot a very long string or line breaks, but I don't think this is the issue.

Why this is happening and how I can fix it?
