Detailed Description

RSA-2048 private key parameters.

WARNING: This struct is intentionally NOT to be declared as a global or static variable. The ONLY valid use is as an automatic (stack) variable inside ssh_rsa_sign(). After the signature is computed, every byte is overwritten via ssh_wipe() before the function returns.

On Arduino, these fields are populated from mbedtls_rsa_context by reading the mpi limbs into 256-byte big-endian buffers.

On native, the fields are set directly by the test fixture or loaded from a DER blob via a minimal DER parser included in ssh_rsa.cpp.
