Overview
The pem package provides PEM encoding and decoding functionality for textual cryptographic keys and certificate chains, compliant with RFC 7468. It supports both strict and lax parsing modes to handle variations in input format, making it suitable for secure key management across platforms. The package enables developers to work with PEM-formatted data reliably in Flutter applications.
Use cases
- Parsing PEM-encoded private keys
- Handling certificate chains in PEM format
- Secure key storage and retrieval
- Interoperability with PKI systems
- Validating PEM block structure
- Supporting TLS/SSL configurations
Key features
- RFC 7468 compliant
- Lax and strict mode parsing
- Supports concatenated PEM blocks
- Cross-platform compatibility
- Simple API for encoding/decoding
- Robust error handling
Suitable for
- Flutter apps requiring cryptographic operations
- Backend integrations with PEM-based protocols
- Security-sensitive applications
- Developers working with certificates and keys
- Projects needing reliable PEM parsing
Considerations
- Requires careful handling of sensitive key material
- May need additional validation for production use
- Not intended for high-performance bulk processing
- Depends on correct PEM formatting in input
- Limited to PEM-specific operations
- No built-in key generation or signing
