ECDSA With SHA1 & SHA256 Support

This pr implements passport verification using P256 ECDSA.

Changes

1. P256 ECDSA Imports

• Added necessary imports to support P256 ECDSA operations.

2. Input Processing and Leaf Calculation (getLeaf function)

• Implemented ECDSA cases.
• For ECDSA:
  • Extracts x and y coordinates from the public key.
  • Uses Poseidon6 to hash x and y coordinates separately.
  • Applies Poseidon3 to combine hashed coordinates with signature algorithm identifier.

3. Verifier Circuit

• Addedpassport_verifier_ecdsaWithSHA1Encryption.circom
• Added passport_verifier_ecdsaWithSHA256Encryption.circom
• Uses dsc_modules[2][k] structure where k is the number of bits.
• Processes signature_r and signature_s components.

4. Register Circuit

• Addedregister_ecdsaWithSHA1Encryption.circom
• Added register_ecdsaWithSHA256Encryption.circom
• commitment hash similar to typescript leak calculation
• Added Verifier circuit logic for signature constraint
• Added test for valid commitment calculation, invalid signature, econtent and mrz checks
