PKCS1

PKCS1 class

Represents signature object regarding PKCS#1 standard.
RSA encryption algorithm and SHA-1 digest method are used for signing.

The PKCS1 type exposes the following members:

Name	Description
PKCS1(image)	Initializes a new instance of the PKCS1 class
PKCS1()	Inititalizes new instance of the PKCS1 class.
PKCS1(pfx, password)	Initializes a new instance of the PKCS1 class
PKCS1(pfx, password)	Initializes a new instance of the PKCS1 class

Name	Description
custom_appearance	Gets/sets the custom appearance.
authority	The name of the person or authority signing the document.
date	The time of signing.
location	The CPU host name or physical location of the signing.
reason	The reason for the signing, such as (I agreeРІР‚В¦).
contact_info	Information provided by the signer to enable a recipient to contact the signer to verify the signature, e.g. a phone number.
byte_range	An array of pairs of integers (starting byte offset, length in bytes) that shall describe the exact byte range for the digest calculation.
timestamp_settings	Gets/sets timestamp settings.
ocsp_settings	Gets/sets ocsp settings.
use_ltv	Gets/sets ltv validation flag.
show_properties	Force to show/hide signature properties. In case ShowProperties is true signature field has predefined format of appearance (strings to represent): ——————————————- Digitally signed by {certificate subject} Date: {signature.Date} Reason: {signature.Reason} Location: {signature.Location} ——————————————- where {X} is placeholder for X value. Also signature can have image, in this case listed strings are placed over image. ShowProperties is true by default.

Name	Description
verify()	Verify the document regarding this signature and return true if document is valid or otherwise false.
