Add Command-Line Integration Tests for AES, RSA, RSA-PSS, HASH, and ECC Operations

[aidangarske]

Description

This PR adds a comprehensive suite of command-line integration tests to verify interoperability between wolfProvider and OpenSSL's default provider. The tests cover key generation, signing/verification, encryption/decryption, and hashing operations using AES, RSA, RSA-PSS, HASH, and ECC.

New Test Coverage

RSA Tests (rsa-cmd-test.sh)

• Tests both standard RSA and RSA-PSS key generation
• Key sizes: 2048, 3072, and 4096 bits
• Tests key generation with default provider
• Tests public key extraction
• Tests sign/verify operations with both providers:
  • Sign with default, verify with wolf
  • Sign with wolf, verify with default
  • Full cross-provider interoperability testing

ECC Tests (ecc-cmd-test.sh)

• Tests ECDSA key generation and operations
• Supported curves: prime192v1, secp224r1, prime256v1, secp384r1, and secp521r1
• Tests key generation with default provider
• Tests public key extraction
• Tests sign/verify operations:
  • Sign with default, verify with wolf
  • Sign with wolf, verify with default
  • Cross-provider verification
• Tests ECDH key agreement between providers

AES Tests (aes-cmd-test.sh)

• Tests AES-128, AES-192, and AES-256
• Supported modes: ECB, CBC, CTR, CFB
• Tests encryption/decryption interoperability:
  • Encrypt with default, decrypt with wolf
  • Encrypt with wolf, decrypt with default
• Random key and IV generation for each test

Hash Tests (hash-cmd-test.sh)

• Tests SHA-1, SHA-224, SHA-256, SHA-384, SHA-512
• Compares hash outputs between providers
• Verifies consistent results across providers

Testing

• Added test scripts to simple.yml CI workflow
• Added 'WOLFPROV_FORCE_FAIL=1` check to simple.yml
• If tests hit [FAIL] will exit with 1 and immediately exit

All tests can be run using:

./scripts/cmd_test/do-cmd-tests.sh

Each test script can also be run individually:

./scripts/cmd_test/rsa-cmd-test.sh
./scripts/cmd_test/aes-cmd-test.sh
./scripts/cmd_test/hash-cmd-test.sh
./scripts/cmd_test/ecc-cmd-test.sh
