Diffie-Hellman Random Number Generation
Question: (Regarding the Chilkat Diffie-Hellman Component/Library) If it is possible, we´d like to know what algorithm is used to generate random numbers because one of our clients is very strict with security and they demand us this information. Answer: The most difficult problem in implementing a good random number generator is in generating a good […]
Decrypt Large Files (10GB)
Question: Can the Chilkat library be used to decrypt a large file (
GZip Inflate/Deflate vs Compress/Uncompress clarification
In a nutshell, a GZIP file consists of a header followed by compressed data (using the “deflate” compression algorithm), followed by a trailer. The GZIP file format is specified here: GZIP file format. The Chilkat GZip component’s Compress* and Uncompress* methods read and write the GZIP file format. Data passed to an Uncompress* method should […]
HTML-to-XML Conversion: DropTagType clarification.
Question: I instantiated the HtmlToXml component correctly but the DropTagType method did not drop the HTML tags as I expected: Htmltoxml.DropTagType(“span font p I”) Htmltoxml.DropTagType(“<span> <font> <p> <I>”) Answer: Call DropTagType once for each type of tag to be dropped (i.e. discarded) from the output. The tag string is case-insensitive: Htmltoxml.DropTagType(“span”) Htmltoxml.DropTagType(“i”) Htmltoxml.DropTagType(“p”) Htmltoxml.DropTagType(“font”)

When the SMTP server decides to actually forward the […]
Using X509 Certificate to Encrypt Data
Question: Do you have any examples of using the Chilkat Encryption component with X509 Digital Certificates to encrypt and decrypt data ? Answer: To use an X509 certificate, the CryptAlgorithm is set to “PKI” and you set the certificate by calling SetEncryptCert. The encryption algorithm may be controlled by using a Chilkat CSP object and […]
Does Chilkat Crypt support 3DES? Yes.
Question: Does the Crypt2 Component support 3DES ?? Setting “CryptAlgorithm” to “3des” or “des” does not change the encoded output when the “EncryptStringENC” method is used. Answer: Yes. The CryptAlgorithm should be set to “DES” (case-insensitive). The KeyLength property determines if it is DES (56 or 64), 3DES (112 or 128) or 2-Key TDES (168 […]

The LastErrorText (or LastErrorHtml / LastErrorXml) will […]
