PublicKey

This is part of GeneXus Cryptography Module. and allows to manage a PublicKey, for asymmetric Encryption.

PublicKey

This data type is available since GeneXus 18 Upgrade 4

Valid key formats

• Encoded Base64 key PKCS8 formatted (.pem extension). It can contain a public key, private key, certificate or both.  
  • Encrypted .pem files are not admitted.
  • Encrypted PKCS8 private keys are admitted since GeneXus 17 Upgrade 2
  • Files with .key extensions are supported since GeneXus 16 Upgrade 11
• PKCS12 certificate or keystore (.p12 or .pfx or .jks extension). It contains only private keys or both.
  • JKS format (JavaKeyStore) is available only for Java implementation.
  • For PKCS12 certificates the file password is needed for both Java and .Net implementations.
  • .Net implementation does not use the PKCS12 alias; it takes the public key from the first certificate on the certificate chain and the first default private key listed on the file.
  • Files with .pkcs12 extensions are supported since GeneXus 16 Upgrade 11
• Every certificate must implement the X509 standard.
• Public keys outside certificates are admitted in PKCS8 format. Supported since GeneXus 18 Upgrade 4

Load

PublicKey.Load(path)

• Input path: VarChar(256) path of the public key file
• Returns: Boolean true if it is correctly loaded

Loads a public key.

ToBase64

PublicKey.ToBase64()

• Returns: Varchar(256) base64 en BER/DER encoded public key

Returns the BER/DER encoded base64 preloaded public key.

FromBase64

PublicKey.FromBase64(base64)

• Input base64: VarChar(256) base64 BER/DER encoded public key
• Returns: Boolean true if it is correctly loaded

Loads a BER/DER encoded base64 public key
