A plsql implementation of some functions/procedures in dbms_crypto

This does include

• pkencrypt/pkdecrypt public/private key encryption/decryption with the following algorithms
  • RSA
• sign/verify using
  • SHA224 RSA
  • SHA256 RSA RSA_X391 withECDSA withECDSAinP1363
  • SHA384 RSA RSA_X391 withECDSA withECDSAinP1363
  • SHA512 RSA RSA_X391 withECDSA withECDSAinP1363
  • SHA1 RSA RSA_X391
• hash and mac function with the following algorithms
  • MD4
  • MD5
  • SH1
  • SH224
  • SH256
  • SH384
  • SH512
  • RIPEMD160
• encrypt/decrypt of raw values with the following algorithms
  • DES
  • 3DES_2KEY
  • 3DES
  • AES128
  • AES192
  • AES256
  • RC4

And this package can be used to create different types of JWT, for instance RS256, ES256 or HS256.

Please note: This package will soon be included in https://github.com/OraOpenSource/oos-utils All additions, changes and bugfixes only will be available at that repository. The package at OraOpenSource will be an "independent" fork. After several years only the hash functions are included, so I will continue to upgrade this package when needed.
