General Information
Policy Type
Description
Digital Sign policy digitally signs data using cryptographic keys or certificates. It generates digital signatures for specified source variables and stores them in target signature variables. This policy provides data integrity and non-repudiation capabilities. ⚠️ Implementation Status: This policy is currently not implemented in Management API. This policy cannot be created or managed through the Management API at this time. This documentation is provided for reference purposes and will be updated when full API support is added in a future release.Endpoints

Notes and Warnings
-
Signature Algorithms:
- RSA:
SHA256withRSA,SHA384withRSA,SHA512withRSA(recommended) - ECDSA:
SHA256withECDSA,SHA384withECDSA,SHA512withECDSA(for elliptic curve) - DSA:
SHA1withDSA,SHA224withDSA,SHA256withDSA(legacy)
- RSA:
-
Key/Certificate Type:
KEY- Uses private key from CryptoKeyInfo (requirescryptoKeyInfoId)CERTIFICATE- Extracts private key from certificate (requirescertificateId)
-
Output Encoding:
BASE64- Base64 encoding (recommended, more compact)HEXADECIMAL- Hexadecimal encoding (human-readable)
- Source Variable: Variable containing data to sign (can be header, parameter, body, etc.)
- Signature Variable: Variable to store generated signature (can be header, parameter, body, etc.)
- Signature Algorithm Variable: Optional variable to store signature algorithm name
-
Key Management:
- CryptoKeyInfo or Certificate must be configured in Apinizer
- Private key must be accessible for signing
- Key must match signature algorithm (RSA key for RSA algorithms, ECDSA key for ECDSA algorithms)
- Performance: Digital signing adds cryptographic processing overhead. Use for necessary integrity/non-repudiation only.
-
Pipeline:
REQUESTpipeline signs request data before forwardingRESPONSEpipeline signs response data before sending to client
- Error Handling: Invalid key/certificate or algorithm mismatch causes signing to fail
-
Deployment: Policy changes require deployment to take effect. Set
deploy: trueor deploy manually. -
⚠️ API Status:
- This policy is currently NOT IMPLEMENTED in Management API
- Attempting to create or update this policy via Management API will fail
- This documentation is provided for reference purposes only
- Full API support will be added in a future release
