📖 NAME

EVP_CIPHER-DES - The DES EVP_CIPHER implementations

🚀 Quick Reference

Use Case	Command	Description
🔐 3DES Encryption (CBC)	EVP_CIPHER_fetch(NULL, "DES-EDE3-CBC", NULL)	DES-EDE3-CBC or DES3
🔐 3DES Encryption (ECB)	EVP_CIPHER_fetch(NULL, "DES-EDE3-ECB", NULL)	DES-EDE3-ECB or DES-EDE3
🔐 Legacy DES Encryption (CBC)	EVP_CIPHER_fetch(NULL, "DES-CBC", NULL)	DES-CBC (legacy provider)
🔐 Legacy DES Encryption (ECB)	EVP_CIPHER_fetch(NULL, "DES-ECB", NULL)	DES-ECB (legacy provider)
🔐 Key Wrapping with 3DES	EVP_CIPHER_fetch(NULL, "DES3-WRAP", NULL)	DES3-WRAP (default provider)

📝 DESCRIPTION

Support for DES symmetric encryption using the EVP_CIPHER API.

🔑 Algorithm Names

The following algorithms are available in the FIPS provider as well as the default provider:

• DES-EDE3-ECB or DES-EDE3
• DES-EDE3-CBC or DES3

The following algorithms are available in the default provider, but not the FIPS provider:

• DES-EDE3-CFB8 and DES-EDE3-CFB1
• DES-EDE-ECB or DES-EDE
• DES-EDE-CBC
• DES-EDE-OFB
• DES-EDE-CFB
• DES3-WRAP

The following algorithms are available in the legacy provider:

• DES-ECB
• DES-CBC
• DES-OFB
• DES-CFB, DES-CFB1 and DES-CFB8
• DESX-CBC

⚙️ Parameters

This implementation supports the parameters described in "PARAMETERS" in EVP_EncryptInit(3).
