EVP_SIGNATURE-DSA.7ossl - Man Page

The EVP_PKEY DSA signature implementation

Description

Support for computing DSA signatures. See EVP_PKEY-DSA(7) for information related to DSA keys.

Signature Parameters

The following signature parameters can be set using EVP_PKEY_CTX_set_params(). This may be called after EVP_PKEY_sign_init() or EVP_PKEY_verify_init(), and before calling EVP_PKEY_sign() or EVP_PKEY_verify().

“digest” (OSSL_SIGNATURE_PARAM_DIGEST) <UTF8 string>
“properties” (OSSL_SIGNATURE_PARAM_PROPERTIES) <UTF8 string>

The settable parameters are described in provider-signature(7).

The following signature parameters can be retrieved using EVP_PKEY_CTX_get_params().

“algorithm-id” (OSSL_SIGNATURE_PARAM_ALGORITHM_ID) <octet string>
“digest” (OSSL_SIGNATURE_PARAM_DIGEST) <UTF8 string>

The gettable parameters are described in provider-signature(7).
