Algorithm Configuration
The following start options are used to configure the security algorithms:
Transition Algorithms (1. June 2017)
- Signature:
- Hashfunction:SHA256 / SHA512
- Signature procedure: sha256RSA / sha512RSA
- Encryption
- Content-Encryption: AES-128 CBC or AES-192 CBC
- Key-Encryption: RSAES-PKCS1-v1_5
Use these JAVA_OPTS:
-Dsigning_algorithm=SHA256WITHRSA or SHA512WITHRSA
-Dsymmetric_encryption_algorithm=AES128_CBC or AES192_CBC
-Dasymmetric_encryption_algorithm=rsaEncryption
New Algorithms (1. Jan 2018)
- Signature:
- Hashfunction (Hash algorithm): SHA-256 or SHA-512
- Signature procedure (Signature algorithm): RSASSA-PSS
- Encryption:
- Key encryption: RSAES-OAEP (with hash function SHA-256)
- Content encryption: AES-128 CBC oder AES-192 CBC
Use these JAVA_OPTS:
-Dsymmetric_encryption_algorithm (Default: AES128_CBC)
-Dasymmetric_encryption_algorithm (Default: id_RSAES_OAEP)
-Dsigning_algorithm (Default: SHA256withRSAandMGF1)
Specific Algorithms for specific Recipients
You can configure different algorithms for different recipients. Recipients are distinguished by their certificate-alias (usually ILN/Mail).
Instead of defining a single algorithm, use the following syntax:
symmetric_encryption_algorithm=Algo1:[alias1,alias2];Algo2:alias3;Algo3
In this example for recipients alias1/alias2 the algorithm Algo1 is used. For recipient with alias2 the algorithm Algo2 is used. For all other recipients Algo3 is used.
Specification:
The property value (right side of equal sign) is a list of algorithm-alias assignments, separated by ;
.
An assignment is a pair of algorithm and aliases, divided by :
. The aliases are optional. An algorithm without aliases is used as fallback value. If no fallback is specified, the default values are used as fallback.
The aliases are a list of at least one alias, separated by ,
. The list can be enclosed by [ ]
.
This syntax works for symmetric_encryption_algorithm, asymmetric_encryption_algorithm, signing_algorithm
.
Don’t be confused when configuring the signing algorithm: You configure the algorithm to be be used for signing of outbound messages, thus the signature by your system/sender. However the configuration is based on the partner/recipient.
