Security¶

Include: Use System\Security.pkg

Security covers certificate handles for HTTP client certificates, binary/text encodings, URI component encoding, and random byte/text generation.

These pages describe observable DataFlex API behavior. They do not expose runtime implementation names. DFSEC_Random fills values with random bytes or readable text; no security-strength guarantee is documented here.

Certificates¶

• Certificates explains certificate formats, handles, and lifecycle rules.
• DFSEC_CertificateFromFile creates a certificate handle from file data.
• DFSEC_CertificateFromString creates a certificate handle from in-memory certificate data.
• DFSEC_CertificateFree releases a certificate handle.

Encoding¶

• Encoding explains the supported encoding formats and common argument rules.
• DFSEC_Encode encodes a string or byte-compatible array and returns a string.
• DFSEC_EncodeUC encodes a string or byte-compatible array and returns UChar[].
• DFSEC_Decode decodes encoded data and returns a string.
• DFSEC_DecodeUC decodes encoded data and returns UChar[].
• DFSEC_EncodeEx encodes bytes from a pointer and returns a string.
• DFSEC_EncodeExUC encodes bytes from a pointer and returns UChar[].
• DFSEC_DecodeEx decodes bytes from a pointer and returns a string.
• DFSEC_DecodeExUC decodes bytes from a pointer and returns UChar[].

Random¶

• Random explains random byte and readable text generation.
• DFSEC_Random fills a destination value with random bytes or readable characters.
